Vault tales 174 – Clades – Eryopiformes

We’re back and with another ‘Clades’ post. This time, it will be a paraphyletic one, ‘Eryopiformes’. This is a crown group of the Temnospondyls, and as the name implies, it consists of the famous big ‘amphibian’ Eryops, but also the rest of the ‘Stereospondyls’–and this group may also include the Gymnophiona, the modern caecillians! AsContinue reading “Vault tales 174 – Clades – Eryopiformes”

Vault tales 169 – Clades – Arthrodira

It has been quite a while since I did a Clades post, and this one will be featuring a group that has lots of figures…but mostly one species. It is (as stated in the title) the placoderm group Arthrodira. Although pretty diverse overall, the most familiar would of course be Dunkleosteus, a giant predator ofContinue reading “Vault tales 169 – Clades – Arthrodira”

Vault tales 128 – Clades – Monotremes

Back again with another Clades post! Earlier this week we looked at a group of so-called primitive fish. This time around, it will be some so-called primitive mammals, the monotremes. As a group, they are (probably? maybe?) the most basal living group of mammals. At the very least, they are united by some shared characteristics–likeContinue reading “Vault tales 128 – Clades – Monotremes”

Vault tales 112 – Clades – Pliosaurs

So we are back with another Clades discussion–one that, unlike other clades posts, does not even begin to cover all of the possible figures out there! That’s right, the predatory beast of Jurassic and early Cretaceous (maybe late Triassic?) seas, the Pliosaurs (properly, the Pliosauroidea…) These animals are famous in books and documentaries for beingContinue reading “Vault tales 112 – Clades – Pliosaurs”

Vault tales 109 – Clades – “Stegocephalia”

So we’re back with another ‘clades’ post, and this one is a very unique one, which requires one heck of a caveat! In this case, it is figures labelled as ‘Stegocephalia’ in my collection database–informal labels, not truly clades. If I was going to discuss all of the stegocephalians, well, it would cover the entirelyContinue reading “Vault tales 109 – Clades – “Stegocephalia””
