We’re here because of this little beast that survived Astraspida

Their structure, although poorly known, has often been used in evolutionary scenarios to illustrate the primitive state of the vertebrate dermal skeleton. Because of the acellular structure of their dermal skeleton, they were initially considered heterostracans

The homostracans were fabulous, but they rarely reproduced.

You should have put that in there. Would have made more sense.

I think my main issue with this idea is that Astraspida is a fish ... a fish living in water when land animals roamed for already 125 million years ... lots and lots of evolution happens in 125 million years ...

I met a guy that looks like this. I'd call him fishlips. I don't know if he had a tale. No, this is not our ancestor. Humans from Adam on down are unique to the earth.
