hollow bones in theropods
Tom Holtz responded to Virginia Tidwell, who suspects that her T. rex femur
may be solid:

I asked these questions before, but got no replies, so I will ask them another
There have been a couple posts that have insinuated that hollow bones are
not strictly a theropod character trait in dinosaurs.
Could anyone provide one or two examples of late Cretaceous dinosaurs that
had hollow long bones and were NOT theropods? Even better, a nice little
list? Certainly, there must be preparators out there who have a lot of this
stuff in their memories :)
And while we are on the subject of long bones and theropods, here is a
question on their toes:
I asked a while back about those deep lateral pits (called co-lateral
fossae in the journals) that grace the distal ends of theropod phalanges. I
presume that those pits are for tendon attachments that are used
to contract the toes/fingers. Question: do any non-theropods have
DEEP fossae on the sides of their phalanges?
