Coprolite (Probable Shark Fecal
This Coprolite, or
fossilized fecal pellet, is likely shark. Note the spiral cast suggesting
passage through a shark's rectum. This specimen was collected
from an Upper-Cretaceous Cenomanian marine mudstone in north central Texas (Turner Park
Member, Eagle Ford Group). Abundant vertebrate remains including cranial
plates, jaws, teeth, vertebra and other skeletal material are found and suggest a robust nektonic community consisting of sharks,
plesiosaurus, mosasaurus, xyphactinus and saurodontid fish
once existed. This specimen is approximately 4.5 cm. long.
