Re: News: Dog finds sail-back synapsid fossil from Carboniferous in Nova Scotia
Unsurprisingly, Jocelyn is right. The ribcage fits a temnospondyl, the
shoulder girdle is a textbook example of a well-ossified temnospondyl
(but would also fit various early amniotes), and the skull can't be
anything but a temnospondyl. The notch is impossible to overlook, and
the shape of the whole thing fits *Dendrerpeton* nicely. I don't have
the copious literature on *Dendrerpeton* here, but from memory I can't
find anything that would prevent the new find from being an unusually
complete individual of *Dendrerpeton*, an early, vaguely basal
temnospondyl. I'll look it up tomorrow if nobody beats me to it.
I agree the thing in the huge eye socket (which fits *Dendrerpeton*
again) is part of the sclerotic ring.
sclerotic ring (unknown in synapsids).
...True! I never noticed!
