Hi Dan, hows it going?

George is also talking about the small oval 'grove' on the back of metatarsal 
II that metatarsal I fits into. It can bee seen in severial theropods. Look at 
Madsen's osteology of Allosaurus, plate 55.  You can see how the
 top mt 1 fits into mt 2, and there is an oval (lightly colored) where the 
lower half of mt 1 fits into mt 2. But it can be best seen on the mt 2 of 
Tyrannosaurus. A paper on what theropods have this oval grove on mt 2 wo
uld be of value. Hmmm... maybe for Dinofest 2000...
