A Relaxing Sunday

By | August 22nd, 2010|Everything Dinosaur News and Updates, Main Page|0 Comments

Sunday – Time for a Break

With just one more full week of August to go, today we have spent sometime in the office just catching up on the jobs that we had been trying to get done this month.  For example, we had some fossil casts to prepare and then send out, plus some more information on fossils to write up for a school project in the Autumn term.  This week, we have just one more engagement, once this is finished we can relax, as all our commitments for the school holidays will have been completed.

Everything Dinosaur

Our new website design is coming along nicely, we had a quick update on progress at Friday’s meeting and everything seems to be going well.  Not sure when the new site is due to go live, but we are hoping that this will take place before the end of August.  Let’s hope so, as we have some new items that have just come back from our test groups and these are ready to be added to our on line shop at Everything Dinosaur.

It will be good to get to through next week, as the events, although very enjoyable, are really  hard work and we have been bombarded with questions from young dinosaur fans.  Some of the events and work with museums has meant that we have had very early starts and the punishing schedule is beginning to catch up with us.  However, with just one more event to go, and with a Bank Holiday coming up, at least we have something to look forward to.

Xiphactinus Fossil Goes on Display (Bully for the “Bulldog Fish”)

Prehistoric Fish Skeleton Goes on Display

The almost complete fossilised skeleton of a giant, swift swimming and deadly Cretaceous predator (Xiphactinus) is going on display for the first time at a Canadian museum.  The Cretaceous may be associated with fearsome reptiles, both on land and in the water, but the plesiosaurs, ichthyosaurs and mosasaurs did not have everything their own way, as some of the nastiest fish ever to evolve also made their appearance in the late Mesozoic.

Xiphactinus

The fossilised fish, an Xiphactinus (pronounced (zee-fak-tin-us) measures nearly six metres long and this weekend it goes on display at the Canadian Fossil Discovery Centre in the town of Morden (Manitoba, Canada).  The Canadian Fossil Discovery Centre houses one of the most extensive fossil collections of marine reptiles in the whole of Canada and the dedicated team of researchers and their assistants are constantly searching the surrounding countryside to find more specimens to add to their collection.

The museum is perhaps best known for its superb collection of mosasaur fossils, including the famous mosasaur known as “Bruce”, perhaps the best preserved of all the Canadian fossil mosasaur material.

Xiphactinus Fossil

The Xiphactinus fossil has been carefully removed from a dig site, a location that was first identified as having excellent fossil finding potential when part of the huge fish’s skeleton was discovered eroding out of sediment back in the summer of 2009.

The fossil is part of a collection of specimens, including mosasaur vertebrae and the leg bones of a giant, prehistoric seabird Hesperornis that have been discovered at the site.  They date from approximately 80 million years ago, a time when the Americas was effectively divided in two by a huge, shallow tropical sea (The Western Interior Seaway).

Xiphactinus (the name means “swift swordfish”), was a powerful hunter, cruising the surface waters of the Western Interior Seaway and hunting virtually any animal that it could fit inside its cavernous mouth.  A member of the teleost fish family (bony fishes), a number of specimens of Xiphactinus have been unearthed, the first being found in Kansas in the 1850s.  The rather compressed and flattened face of this large fish has led to it being nicknamed “the bulldog fish” and it has been described as the ugliest fish to have ever existed.

Perhaps the most famous fossil of Xiphactinus is the amazing “fish within a fish” specimen.  George Sternberg, (a member of the famous Sternberg family who between them discovered a number of prehistoric animal specimens in North America) found this fossil in 1952 , it revealed a Xiphactinus with a fish measuring nearly 2 metres long in its gut.  This was the last meal that this Xiphactinus ate and it probably was the cause of its death.  With their ability to open their mouths very wide, these fast swimming predatory fishes were capable of swallowing large prey, however, in this instance this particular Xiphactinus probably had a mouth that was bigger than its stomach.
