Mesozoic Havoc #2 Traditional Cache

This Cache is the second of 3 creatures that evolved in that time ERA and some how they ended up here in Rapides Parish .  Confused as to where they are.  They are stressed out and creating Havoc in this unfamiliar environment. Find them and help calm them down!

This cache is a bison tube with a log. Please place cache back in the same area you found it in.

The Mesozoic Era was the time from 248 million to 65 million years ago. During the Mesozoic, the Earth was very different than it is now. The climate was warmer, the seasons were very mild, the sea level was higher, and there was no polar ice. Even the shape of the continents on Earth was different; the continents were jammed together at the beginning of the Mesozoic Era, forming the super continent of Pangaea, but would start breaking apart toward the middle of the Mesozoic Era.

Not sure these green things here are edible, looking for the tree that is host to this states flower.
