Louisianaâs First Dinosaur
Louisianaâs first dinosaur fossil was found in 2004 at
the TVOR SE vertebrate fossil location in Fort Polk,
Vernon Parish, Louisiana, as discussed and illustrated
by Schiebout et al. (2004). The fossils found at this
location include a wide variety of fossil Miocene
vertebrates and reworked Cretaceous foraminifera.
The lone dinosaur fossil, LSUMG 12229, is a âsmall,
sharp theropod toothâ that is consistent of having
come from a dromaeosaur. This fossil was eroded
from terrestrial Cretaceous deposits to the north
and transported by Miocene rivers into Louisiana.
