Jumpin' dinos

["Matthew Bonnan" <mbonnan@hotmail.com>]

For some reason, a message I thought I had sent out to all last night didn't 
make it out.  Stanley Friesen, if you got my message, could you please 
forward my message to the list??  Thanks.

Matt Bonnan

In the message, I mentioned the fact that no dinosaurs or guys like 
Marasuchus have a calcaneal (heel) tuber.  In jumping animals (kangaroos, 
for ex.), the calcaneal tuber is huge and allows the gastrocnemius to insert 
on a nice lever arm along with the plantaris and soleus muscles in the form 
of the Achilles tendon.

So as not to potentially repeat myself, hopefully Stan will send out the 
copy of my message intended for everyone.

Later
