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 149 – Clades – Salamandroidea

It’s been a while, but here we are with a new Clades post. Since then, I have been reorganizing my database and how the clades are organized. So when this one came up–‘Salamanders’–I realized that I could break that down a little bit. Especially because there are a fair number and this post was goingContinue reading “Vault tales 149 – Clades – Salamandroidea”

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 127 – Clades – Chondrostei

I am back with another Clades post. This one is exciting because it features one of my favorite fish groups! It’s also daunting because I have a lot of representatives of this group (unlike most of the ones I’ve done) which means more to say. And also trying to sort out photo presentation… As itContinue reading “Vault tales 127 – Clades – Chondrostei”
