Thanks all for the interest. After dying in various ways (drowning, jumping off a cliff, getting nailed and owned by a alpha megladon) the winner was the admin code. Thanks Morgan Haley. Here is the codes I found. If you find any other variations please share.
Use code:

Note: in <___> replace with but don't use the quote marks:
g (for a skin for a Giga)
m (monosaur)
p (parasaur)
"q" or "quetz" (quetzal)
"r" or "rex" (rex)
s (stegosaurus)
t (triceratops or trike)
