Vault tales 179 – Clades – Euchondrocephali

Already another ‘clades’ post, but this time one with a few more figures at least! This one will be Euchondrocephali–a group of shark-like chondrichthyan fish that are more closely related to the holocephalans (the modern ratfish Chimaera and elephantnose fish Callorhinchus). The funny thing is that for the longest time, these fish were assumed toContinue reading “Vault tales 179 – Clades – Euchondrocephali”

Vault tales 178 – Clades – “Sauropoda”

Today we have another ‘Clades’ and this time…it will take more explanation? When I revamped my database taxonomic details, I realized that some groups were very heavily lumped into one category–even though many groups fit in as ancestors to others, etc. Some groups were also more tightly defined than others, often based on how IContinue reading “Vault tales 178 – Clades – “Sauropoda””

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”
