The Tyrannosaurus does in fact have an extremely tiny third finger, you can see it in its skeleton. GreatGatsby 03:49, 9 September 2005 (UTC)
Just a carpal, as I recall, not a full digit. 69.227.175.66 05:01, 27 October 2005 (UTC)
- Check a skeleton, it is not just a carpal. GreatGatsby 02:52, 20 November 2005 (UTC)
- It's a metacarpal :o). In all probability it was fully enfleshed in life in one unit with the other metacarpals and not apparent as a "finger", though it is of course part of the digit. So T. rex had three digits but two "fingers".--MWAK 11:00, 18 February 2006 (UTC)

False Group?
"Some believe Tetanurae is a false group consisting of two entirely seperate lineages..."
I've never seen this anywhere. Does someone have a reference?
"Oddly enough, recent Ceratosaurus finds indicate that the species may be in fact a basal Tetanurae carnosaur..."
This needs a reference, too. And since Tetanurae is defined as excluding Ceratosaurus, this is actually impossible.
I'm removing these until someone provides a reference.--Keesey 23:14, 14 July 2006 (UTC)
