Just a quick question: How far down do theropod ribs proceed down the
vertebral column? I can't remember what I've seen off the top of my head,
I was wondering if anyone else knew if they went all the way to the sacrum
or stopped before the pelvic region.
Theropods had two dorsal ribs for every dorsal vertebra, all the way to the
sacrum. Here's what I would like to know- what are sacral and caudal ribs?
I hear about caudal ribs in relation to diplodocids and some other
sauropods. Are these just transverse processes? Are sacral ribs transverse
processes or actual ribs.
I have an excellent jpg of the rib cage of Giganatosaurus, taken from
directly underneath the mounted skeleton, looking up. If there is
interest, and you don't mind me answering later on (like Later On) I
could forward it to interested parties.
