Estemmenosuchus

In Depth        Although other herbivorous therapsids like Styracocephalus also had head crests,‭ ‬Estemmenosuchus had by far the most elaborate head ornamentation.‭ ‬These crests varied between the two species,‭ ‬but superficially the head ornamentation resembled short deer antlers.‭ ‬The horns of Estemmenosuchus grow upwards from the frontal skull bones and seem to have primarily been display … Read more

Clelandina

In Depth        Although often compressed,‭ ‬and incomplete,‭ ‬Clelandina skulls have been noted as being particularly broad while having short snouts.‭ ‬These are two significant developments that may indicate that Clelandina had a particularly strong bite force.‭ ‬A wider skull would allow for greater room for larger‭ (‬and hence more powerful‭) ‬jaw closing muscles,‭ ‬while the … Read more

Dimacrodon

In Depth        When first described in‭ ‬1953,‭ ‬Dimacrodon was thought to be an anomodont therapsid.‭ ‬Later analysis however has suggested that the partial remains of Dimacrodon night actual be those of a pelycosaur.

Casea

In Depth        Casea is typical of the caseids in that it has a large body with a disproportionately small head. It is generally considered that Casea was a slow moving, low browsing herbivore. The teeth are short and short and ‘peg-like’, possibly for stripping the fronds of ferns. The ribs of Casea are greatly enlarged … Read more
