Thirteen Batches of Frogspawn in the Office Pond

By | March 3rd, 2024|Adobe CS5, Animal News Stories, Educational Activities, Main Page, Photos|0 Comments

Common frogs (Rana temporaria) began breeding in the office pond very early this year. The first batch of frogspawn was observed on the morning of Saturday, the 18th of February. Frog activity had been observed in the pond a few days earlier. The spawning season has stared early, perhaps because of the mild, wet weather. February the 18th is the earliest date in the year that we have recorded frogspawn. Last year (2023), the first frogspawn was recorded on the 28th of February. This was the first time that we had recorded frogs spawning in February.

We estimate that by this weekend, a total of thirteen batches of frogspawn had been laid. The number of frogs seen in the pond has rarely exceeded four or five. However, other frogs must be visiting the pond and breeding during the night or in the early morning.

A Record Amount of Frogspawn

A spokesperson from Everything Dinosaur commented:

“Although we cannot be certain, there could be a record amount of frogspawn in the office pond. We think there are thirteen batches in total. All the eggs were laid in a shallow part of the pond.”

Hopefully, the sudden cold snap with overnight frosts will not have harmed the eggs. We are looking forward to watching the tadpoles hatch.

Frogspawn Discovered in the Office Pond

By | February 18th, 2024|Animal News Stories, Educational Activities, Main Page, Photos|0 Comments

We have frogspawn in the office pond. Today, a clump of frogspawn was observed in a shallow area of the office pond. Frogs had been spotted in the pond a few days ago, it seems that the spawning season has started. This is the earliest date in the year that we have recorded frogspawn. Last year (2023), the first frogspawn was recorded on the 28th of February. This was the first time that the frogs have spawned in February. This year, the frogs have begun spawning even earlier.

Common Frogs (Rana temporaria)

The spawn was produced by Common frogs (Rana temporaria). Observations by team members suggest that there were four frogs in the pond. The pond has been created to attract wildlife and frogs have laid their eggs in the pond each spring since 2008. For many years the frogs spawned around the third week of March. However, there is a distinct trend for recording spawning much earlier in the year.

Could this be a consequence of global warming and climate change?

It has certainly been very mild over the last week or two. Temperatures of 13-14 degrees Celsius have been recorded in the northwest of England. The average temperature for February in the Manchester area of England would normally be expected to be around 4-7 degrees Celsius.

Frogspawn Laid in a Shallow Part of the Pond

The frogs have laid their eggs in a shallow part of the pond. Eggs are not normally laid in this part of the office pond. Folklore suggests that if frogs lay in the shallows, then the next few weeks will be mild but wet. We will continue to observe the pond to see if more frogs arrive and more spawn is produced.

Lungfish and the Remarkable History of Fossil Holes

By | February 16th, 2024|Adobe CS5, Animal News Stories, Main Page|0 Comments

Yesterday, Everything Dinosaur team members posted up an article that provided information on the evolutionary history of burrowing vertebrates. The first vertebrates to dig burrows were probably lungfish. These animals were similar to extant lungfish, animals such as Neoceratodus forsteri, the Australian lungfish. This taxon is also referred to as the Queensland lungfish.

Ironically, it is thought that this species of lungfish does not enter a dormant state (aestivation), by producing a mucous cocoon and burying itself in mud. Neoceratodus forsteri inhabits slow-moving rivers and reservoirs, primarily in south-eastern Queensland. In contrast, the African genus Protopterus does dig burrows. Protopterus is distantly related to the Australian lungfish. During the dry season when lakes tend to dry up, this fish excavates a burrow and buries itself in the mud. It enters a state of dormancy (aestivation), enabling it to survive whilst it waits for the water to return. During aestivation Protopterus is able to reduce its metabolism to 1/60th of its active state.

A team of researchers, including scientists from the Museum für Naturkunde Berlin examined the origins and early evolution of vertebrate burrowing behaviour. Their paper was published in Earth-Science Reviews.

To read Everything Dinosaur’s article about this new research: Digging into the History of Burrowing Vertebrates.

The Scientific Paper

The scientific paper comprises a short overview of convergent morphological and behavioural adaptations seen in modern fossorial taxa. The researchers also document the diversity of extant vertebrate burrows. In addition, the team reviews the fossil record of inferred vertebrate burrows and fossorial vertebrates from the Devonian to the Triassic. Results highlight a probable Devonian earliest occurrence of fossoriality in continental vertebrates (Dipnoi – lungfishes).

The earliest lungfish taxa were mostly marine animals. However, after the Carboniferous, lung fish fossils are confined to deposits laid down in freshwater environments.

The Australian lungfish specimen at the London Natural History Museum is displayed next to a model of a Protopterus burrow. This can confuse visitors, it was stated earlier in this article that not all lungfish exhibit this burrowing behaviour.

A Spectacular Nile Crocodile Skeleton on Display

By | January 29th, 2024|Adobe CS5, Animal News Stories, Main Page, Photos|0 Comments

Team members at Everything Dinosaur photographed a spectacular Nile crocodile skeleton. The skeleton is on display at the London Natural History Museum. Recently, Everything Dinosaur wrote a short blog post about the reptile exhibit at the Museum.

To read Everything Dinosaur’s earlier crocodilian post: A Fascinating Nile Crocodile Exhibit.

The Nile Crocodile Skeleton

As male Nile crocodiles tend to be much bigger than the females, we suspect the skeleton represents a male. The Nile crocodile skeleton could have come from a crocodile farm. Perhaps the skeleton came from a zoo. It is part of an exhibit that looks at extant reptiles. The exhibit also includes a large, stuffed Nile crocodile specimen.

A spokesperson from Everything Dinosaur stated:

“This large exhibit permits visitors to get a really good look at the skeleton of a large crocodile. The exhibit includes examples of crocodile stomach contents. The skeleton is impressive, although this reptile is dwarfed by the specimens in the Dinosaurs Gallery.”

Fascinating Nile Crocodile Specimen on Display

By | January 25th, 2024|Adobe CS5, Animal News Stories, Main Page, Photos, Photos of Everything Dinosaur Products|0 Comments

Team members at Everything Dinosaur photographed a stunning Nile crocodile specimen on display at the London Natural History Museum. The Nile crocodile (Crocodylus niloticus) is the largest freshwater predator in Africa. Males can grow up to six metres in length and weigh more than a tonne. As such, the Nile crocodile can be considered as the second-biggest extant reptile. Only the Estuarine crocodile (Crocodylus porosus) is larger.

The stuffed crocodile specimen measures more than three metres in length. It is part of an exhibit that highlights the diversity of vertebrates found on Earth today. It is exhibited alongside a Crocodylus niloticus skeleton.

The Nile Crocodile (Crocodylus niloticus)

Phylogenetic analysis has revealed that this African crocodile is more closely related to American crocodiles such as the Orinoco crocodile and the Cuban crocodile than it is to other African crocodile species. Several subspecies of Crocodylus niloticus have been proposed.

A Man-eater

These crocodiles are estimated to kill many hundreds of people each year. The total number of attacks on humans is unknown as many attacks are unreported. Nile crocodiles tend to be much more aggressive than many other crocodilians. However, these crocodiles live in close proximity to human populations throughout most of their range. As contact is more frequent, this may explain why the number of Nile crocodile attacks remains disproportionately high. Most attacks on humans are made by crocodiles that exceed three metres in length. However, smaller crocodiles, animals less than two metres in length are capable of overpowering children.

A number of programmes are in place to help reduce the threat of crocodile attacks, by providing alternative access to water through the construction of wells and safe water gathering places. It is hoped that educating local fishermen about crocodile behaviour can reduce the risk of attack.

Commenting on the museum crocodile exhibit a spokesperson from Everything Dinosaur stated:

“The exhibit looks at the evolutionary history of vertebrates. The reptile section is particularly interesting with many stuffed specimens on display.”

Both figures are the same sculpt, just the colouration depicted by the subtle painting schemes is different. Each figure is supplied in two parts. Some assembly is required, the tail has to be fitted into the body. When assembled the alligator figure measures approximately 62 cm long. The highest point of the back is around 10.5 cm off the ground. Across the torso, the impressive alligator model is about 10 cm wide.

Rebor Models and Figures

Rebor has extended its range to include extant reptiles as well as prehistoric animals. The two alligator figures join the recently introduced “Lonesome George” giant tortoise.

A spokesperson from Everything Dinosaur commented:

“The two new alligator models are extremely detailed. It is recommended that the tail piece is gently heated before inserting it into the body piece. Hot water can be used to heat up the joints. However, we urge caution as the figure is hollow and if hot water is used, it would be necessary to drain any excess water before attempting to secure the tail.”

Boom in Mammoth Tusk Sales Threatens Living Elephants

By | October 15th, 2023|Adobe CS5, Animal News Stories, Dinosaur and Prehistoric Animal News Stories, Main Page, Palaeontological articles, Photos/Pictures of Fossils, Teaching|0 Comments

The boom in the trade for mammoth tusks threatens extant elephant populations and their habitats. This is the conclusion of newly published research from the University of Portsmouth.

Conservationists and campaigners fear an increase in the buying and selling of mammoth tusks poses a direct threat to elephants. The trade in “ice ivory” was banned in the UK in 2018. The ban was imposed following a Portsmouth University led investigation into the British antiques trade of the material.

The Trade in Mammoth Tusks

Earlier this year (2023), it was announced the Ivory Act would be extended to protect five more endangered CITES-listed species, including the hippopotamus, narwhal, walrus, orca and sperm whale. However, new research highlights the unregulated sale of mammoth tusks needs to be addressed. The species fall outside of the regulation of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). This is an international, multi-government agreement set up to ensure the survival of animals and plant species.

The authors argue that while woolly mammoths became extinct thousands of years ago, their lives and ultimate demise has much to teach us about how we conserve and protect existing elephant populations.

What About Other Prehistoric Elephant Genera?

Everything Dinosaur notes, that many species of extinct elephant had large tusks. Whilst the tusks eroding out of melting Siberian permafrost might usually be associated with the Woolly Mammoth (Mammuthus primigenius), tusks from other extinct species might be traded too. For example, tusks from the American Mastodon (Mammut americanum) or the Columbian mammoth (Mammuthus columbi) found in North America might also be bought and sold.

Prehistoric Elephant Tusks Labelled as Ivory from Extant Species

Lead author in the recently published paper, Dr Caroline Cox (University of Portsmouth) commented:

“There’s evidence traders are trying to sustain the illegal ivory market with mammoth tusks, by intentionally mislabelling ice ivory as elephant ivory. Modern elephants and woolly mammoths share a common ancestor, so their tusks have close similarities. Instead of profiting from these new discoveries, we should be learning from them – how mammoths lived and how they died – to help protect their endangered relatives.”

It is estimated the illegal wildlife trade to be collectively worth between $15-22.5 billion USD a year. This puts the trade on a par with the illegal arms trade, the illegal drugs trade and the trade in human trafficking.

Schreger Lines in Elephant Ivory

Co-author of the study, Luke Hauser (University of Portsmouth) explained:

“Structurally, mammoth ivory is fundamentally identical to elephant ivory. Both have Schreger lines, which are distinct characteristics of the species.”

The majority of the ivory coming out of Siberia is woolly mammoth, but because evolution is a slow process there would have been crossovers between their characteristics and their predecessors. In theory, a trader could have a document claiming a tusk is from a Steppe Mammoth (M. trogontherii) when in fact it is actually a Woolly Mammoth (M. primigenius). Conservationists could not argue otherwise without an expensive and lengthy DNA test.

It is more than a decade since eBay announced its own complete, worldwide ban on ivory sales. An on-line post stated that the global ban would “protect buyers and sellers, as well as animals in danger of extinction”. Unfortunately, recent studies have shown that sellers of illegal wildlife products operate on the dark web, rather than more openly through on-line social media and auction platforms.

The Trade in Mammoth Tusks Damages the Fossil Record

Dr Cox explained:

“While mammoth tusks continue to be in demand, particularly in the Far East, the Siberian tusk hunters of Yakutia recover only what the buyers want – the ivory. The remains of the mammoth are left behind and lost to science.”

The mining of mammoth tusks is dangerous. It is often illegal, and it damages the environment. The law of the Russian Federation states that only mammoth tusks that have come to the surface, usually as a result of the permafrost melting, can be harvested. However, this is extremely difficult to enforce. Miners can speed up the erosion process by using high pressure hoses to blast the permafrost. The industrial mining of the permafrost also releases huge amounts of greenhouse gases such as methane. This is leading to accelerated global warming.

The paper, published in the “Journal of International Wildlife Law and Policy”, states that the best and most effective way of tackling issues surrounding the “ice ivory” trade is international cooperation from nations sharing resources and intelligence.

A Huge and Rare Estuarine Crocodile Skull

By | October 10th, 2023|Animal News Stories, Main Page, Photos|0 Comments

Team members at Everything Dinosaur photographed a huge estuarine crocodile skull on display at a London museum. The stunning skull was part of an exhibit demonstrating reptile anatomy at the Grant Museum of Zoology (London).

An Estuarine Crocodile Skull

The Grant Museum is currently closed. It is undergoing a redevelopment programme. Everything Dinosaur visited this amazing museum in 2018. The Grant Museum of Zoology and Comparative Anatomy was established in 1827 by Robert Edmond Grant (1793-1874). It was established to serve as a teaching collection at the newly founded University of London (later University College London).

We photographed the estuarine crocodile skull in anterior view. The estuarine crocodile (Crocodylus porosus) is the largest living reptile. Some specimens weigh more than a tonne. It is a formidable predator, and it is also referred to as the saltwater crocodile or saltie.

These crocodiles inhabit both freshwater and brackish environments. They have been observed swimming far out at sea. This may explain their extensive geographical distribution. These crocodiles are found from India’s eastern coast to northern Australia. They are apex predators and generalist carnivores. This crocodile is regarded as a maneater and sadly, there are numerous fatal attacks reported each year.

Once hunted for its skin, the numbers of this species of crocodile have dramatically increased since legal protection was implemented.

The Grant Museum of Zoology and Comparative Anatomy

The Grant Museum of Zoology and Comparative Anatomy is an amazing place to visit. It is full of stunning skeletons demonstrating the diversity of vertebrate life on Earth. It is also home to a vast collection of invertebrate specimens. If in London in 2024, a visit to this museum is recommended.

Birds that Evolve Greater Complexity are Less Biodiverse

By | September 24th, 2023|Adobe CS5, Animal News Stories, Main Page, Photos|0 Comments

Newly published research studying bird evolution suggests a link between complex skeletons and reduced biodiversity. As birds develop more complex anatomies, they also decrease in diversity, with fewer species as they become more specialised within specific ecological niches.

Studying Patterns in Bird Evolution

Researchers at the Milner Centre for Evolution at the University of Bath collaborated with colleagues at the University of Lincoln, University College London and the Chinese Academy of Sciences. Their findings have been published in the journal “Nature Communications”.

The team looked at 983 species across all major groups of living birds and measured the complexity of their skeletons by comparing the bones in their fore limbs (wings) and hind limbs (legs).

They found that less complex birds – those with a smaller differences between their fore and hind limbs – had more species diversity than those with higher complexity and a larger difference between their limbs.

As an example, birds such as pigeons, gulls and songbirds (passerines) have low skeletal complexity but a high diversity of species living in varied habitats across the world.

At the other end of the spectrum, flamingos, and ostriches have short wings in comparison to their legs, and so have more complex limb skeletons. Groups with more complex skeletons may occupy smaller niches and are less able to subdivide those niche spaces in order to produce new species.

Trapped in an Ecological Niche

Whilst evolution can produce forms with lower complexity, these findings suggest that birds with more complex skeletons have become more specialised over time and so more developmentally entrenched. This may make them less likely to evolve back to become simpler again. In essence, Aves with complex skeletons may find themselves trapped within a specific ecological niche.

Causes of Biodiversity

Professor Matthew Wills, (Milner Centre for Evolution at the University of Bath) explained:

“We wanted to understand what causes some groups of birds to be species rich and others to be species poor – although ecology obviously plays an important part, it doesn’t account for the huge differences we see in biodiversity.”

Professor Wills added:

“The received wisdom is that there is no direction to evolution – that selection can act in any direction. Our study suggests that, in birds at least, the more they specialise, the less they are able to give rise to new species.”

A Case of Putting All Your Eggs in One Basket

The scientists also found that birds with more complex skeletons were generally more ecologically specialised, occupying fewer habitats and foraging for food in less varied ways.

Lead author of the paper, PhD student Andrew Brinkworth (Milner Centre for Evolution at the University of Bath) stated:

“Species can evolve to be specialised, and fill very small niches. However, in doing so, they restrict the number of routes they can evolve further, meaning they are likely to be less resilient to changes in the environment such as those caused by habitat loss, disruption to food chains and climate change.”

Andrew added:

“From our findings we predict that birds with more complex skeletons and less diversity will be at greater risk of extinction from these changes.”

Wider Implications for Bird Evolution and Animal Life

The researchers intend to broaden their research to see if this pattern is repeated in other animal groups. It would be interesting to see if this relationship between complex skeletons and reduced biodiversity can be identified in extinct groups, including theropod dinosaurs.

Could such a pattern be identified in the Theropoda to bird evolution lineage?
