New South African Permian Dicynodont Described

Dicynodont with a Big, Bulbous Nose – Bulbasaurus phylloxyron

The Karoo Basin of South Africa is famous for its Permian fossils.  The rocks exposed in this part of the world, trace the geology of what was to become known as the super-continent of Gondwana, from the Late Carboniferous through into the Early Jurassic.  It is the abundance of Permian-aged Tetrapod fossils from the Beaufort Group of strata and its rock formations that have provided palaeontologists with a great deal of information about terrestrial life before the rise of the dinosaurs.  Researchers from the Museum für Naturkunde Berlin and the University of Witwatersrand have announced the discovery of a bizarre-looking new type of dicynodont, this critter may have been quite small, but it did have large tusks and strange, rough boss on its nose.

Bulbasaurus phylloxyron

Described from skull material that was discovered preserved in 1.5 metre-deep mudstone, it is thought the head of this reptile was transported by a flood event before coming to rest in the mud.  Over millions of years the mud became rock, preserving the skull and some of the teeth, including evidence of an impressive pair of tusks (located in the upper jaw).

The photograph above shows two views of the holotype material (SAM-PK-K11235) taken from the excavation site.  Picture (A) shows the skull in left lateral view, whilst (B) shows the dorsal view.  The geological hammer provides scale.  The fossil material was discovered at Driekoppe, Vredelus, Fraserburg, Western Cape Province, by Dr Roger Smith (University of Witwatersrand), it was during a visit to view the collection of Permian fossils that dicynodont specialist Dr Christian Kammerer (Museum für Naturkunde Berlin), noted the skull showed a number of unusual features, most of which are associated with much younger types of Dicynodontians.  Further study led to the establishment of a new species (B. phylloxyron).  The genus name means “bulbous nose”, a reference to the large and roughened boss located on the naris bone.

Key

sq = squamosal, qj =quadratojugal, apt = anterior pterygoid ramus, ec = ectopterygoid, fr = frontal, la = lacrimal, mx = maxilla, na = nasal, pmx = premaxilla, pb = base of postorbital bar, po = postorbital, prf= prefrontal and ? indicates an unidentified bone.  The area shaded grey in the line drawing represents matrix.

 Significant Permian Fossil Discovery

Bulbasaurus was found in rocks that have been dated to the early Lopingian Epoch of the Late Permian.  It lived around 259 million years ago.  The fossils are significant as Bulbasaurus is the oldest known member of a family of dicynodonts known as the Geikiidae.  Its discovery helps to fill in a gap in the early fossil record of this important group.

The scientific paper: “An early geikiid dicynodont from the Tropidostoma Assemblage Zone (late Permian) of South Africa”, published in the journal PeerJ.

Happy Smiling Dinosaurs

Year 1 Make Paper Dinosaurs

After a busy morning delivering two dinosaur themed workshops to Year 1 classes at Prescot Primary, our dinosaur expert was presented with a couple of paper dinosaurs that some of the girls had made.  Origami dinosaurs, what a super idea!  Rolled up white paper is a cheap and effective way to make pretend dinosaur bones for use in art classes building dinosaur skeletons, but we had not been presented with paper dinosaurs before.  The two dinosaurs, one a herbivore, the other a carnivore (we explored these terms along with omnivores with the children), had huge grins on their faces, they look like very happy dinosaurs to us.

Our dinosaur expert was informed that one of the models was a Diplodocus, the other a Tyrannosaurus rex.  During the visit to the school by Everything Dinosaur, we were asked lots of questions by the children (and the teachers too).  We were asked how to pronounce Diplodocus?  Good question, we tend to pronounce this long-necked dinosaur as “dip-ploh-de-kus”, whilst others prefer to use  “dip-ploh-dok-us”, both forms of pronunciation are fine by us.

Other questions included wanting to know whether dinosaurs were warm or cold-blooded and whether chickens were in fact dinosaurs?  What a super set of questions from Lower Key Stage 1.

Palaeontologists have suggested that dinosaurs might have had lips.  Perhaps they could pull faces, maybe they were even capable of smiling, now there’s an interesting thought, something to explore with Year 1 as an extension after the dinosaur workshop in school.
