    I decided to make an academic webpage for myself. Also contains tutorials and code for methods I’ve designed. Any comments or criticisms welcome

    There are nine - **NINE** - Collections Assistants jobs on offer at , to document and move a quarter of a million objects to a new facility. Is this the exciting chance you were waiting for?

    Paper by Jones et al on the evolution of the vertebral column in the mammal line: the separation into the different regions actually predates the functional diversification, which correlated with the change in breathing mechanism

    The Karoo is by far the most productive source of mid-late Permian terrestrial fossils, but this can make it easy to forget it is an extremely aberrant fauna for the time. One oddity is the extreme rarity of amphibians. Rhinesuchus and it’s immediate kin are all we have

    For its Rhinesuchus, a 3m long temnospondyl amphibian from the mid-late Permian (~265-255Mya) of the Karoo, South Africa. Skulls on display at the Evolutionary studies institute in Johannesburg

    I’m just going to post this here and see how many vertebrate palaeontologists I can cause to spontaneously combust

    gives us Kenomagnathus, a new pelycosaur (stem-mammal from the Carboniferous) from Spindler 2020. Well, I say new, the specimen’s been around for a while, but was assigned to another species.

    During the Late Cretaceous (~80mya), sea levels rose rapidly, and a seaway ran down the middle of North America. In that sea you would find these guys. They seem to have no inclination to go on land; their legs arent really orientated to support them out of water.

    For we have Hesperornis from the American Museum in New York, a stem bird with teeth. No scale, the whole thing is over 1.5m!

    Struthiocephalus is a tapinocephalian, a lineage of stem mammals that were the dominant herbivores for a brief stint in the middle Permian. The group died out in a minor mass extinction ~260mya, barely 10my after their first appearance (pic from Day et al 2018)

    Its duck-face was suggested in the 50s to be an adaptation for feeding on aquatic plants like an ugly 3m long duck. It was even suggested that the bone structure of the nostrils indicated valves to seal them off under water.

    today brings us a Struthiocephalus skull from the evolutionary studies institute in Johannesburg. Specimen hails from the middle Permian (~265 mya) of South Africa. Nose on the right

    Anyway, back to Spindler's paper. They provide a new reconstruction of the smushed skull, calling into question a number of the characters previously used to support the therapsid affinity. They decide its a pelycosaur, but more primitive than I found, outside sphenacodontids

    (Bit of shameless self-promotion, myself and published a paper in 2017 where it came out as a weird knobbly sphenacodontid, in the group containing Dimetrodon)

    However, in the 90s, Tetraceratops was suggested to be a therapsid. At ~275 million years old, this made it, at that time, the oldest known therapsid. Since then, debate has raged surrounding its pelycosaur/therapsid status.

    Tetraceratops was first described as a pelycosaur in 1908, thought to be closely related to sphenacodontids like Dimetrodon (left), or later moved to eothyridids like Vaughnictis (right)

    So some background. Synapsids (the lineage leading to mammals) during the Permian are divided into two groups: the pelycosaurs (a grade of six families dominating in the early Permian) and the therapsids (the larger group containing mammals, dominating in the late Permian)

    Its , with a new paper from Spindler on the mysterious stem mammal Tetraceratops. Not the nicest specimen so I labelled some bits to orientate. Scale bar 5cm. Thread on exciting points follows:
