Who wages his eternal conflict against Baron Homoplasy and that dreaded
team, the Unresolved Polytomies!!
(Ah, well, I guess the secret is out. No more pretending to be a
mild-mannered paleontologist from a suburban university... :-).
On a more serious topic, I finally got to see the latest report (in Science)
on the supposed Middle Triassic prosauropods from Madagascar. While I
wouldn't be surprised at a Middle Triassic dinosaur per se (seeing as the
Carnian is the early part of the Late Triassic, and the
saurischian-ornithischian split had demonstrably occured by then), I wish
the support for the Middle Triassic Epoch for the unit was based on
something other than vertebrate biochronology. Some good radiometric or
palynological or paleomag dates would go a long way in convincing me.
