This guy would fit right in a modern fish tank but for a few unusual features, yet it died out even before the dinosaurs showed up.

I like this. I would've love seeing this with a bit more of post work... like debris and such.

Thos eearly vertebrates were kinda cute.  Doesn't look terribly mobile though does it? :)
NTamura's avatar
Well, they lack paired fins so could not maneuver much, and they were protected by a bony armor... so no they weren't terribly mobile... :)

wonder if amphibians rule the earth...

Amphibians? What amphibians?
Mussadiq's avatar
just a thought :)

The earliest known American vertebrate
NTamura's avatar
Nope, that would be Pirchancaspis from South America (Early Ordovician)... Astraspis and Eriptychius are Late Ordovician... And of course, we have to ignore the conodonts ;)
avancna's avatar
Let me amend that, then, "First North American craniate vertebrate"
That statement is more or less correct?
NTamura's avatar
OK.  Wasn't Anatolepis also found in North America, though?
avancna's avatar
I thought it was found in Turkey.
NTamura's avatar
Ah? Maybe... Have to look it up.
avancna's avatar
Both of us are wrong: Anatolepis is from Early Ordovician Spitzbergen
NTamura's avatar
The holotype is, but Anatolepis-like remains turned up elsewhere dating from the Cambrian to the Silurian...
