Re: Giant flightless birds
T. Mike Keesey covered this, but why not add Carnotaurus (sp?) to the
list of theropods that have absolutely tiny three digit hands and
The question is, does you think Carnotaurus, Torvosaurus, spinosaurs,
etc. also evolved from flying ancestors? If not, you cannot use small
arms in other theropods as evidence for your hypothesis. Does this
falsify your hypothesis? No, but it does not support it either.
Torvosaurus appears in the Late Jurassic, the same time frame that
Archae. appears. Or do Archae. and the flightless dinosaurs diverge
prior to the Late Jurassic if your hypothesis is correct?
