The San Lucas Formation is a geologic formation in Mexico. It preserves fossils dating back to the Cretaceous period.
The Torcer Formation is a geologic formation in Texas. It preserves fossils dating back to the Cretaceous period.
The Travis Peak Formation is a geologic formation in Texas. It preserves fossils dating back to the Cretaceous period.
The Cuchillo Formation is a geologic formation in Texas. It preserves fossils dating back to the Cretaceous period.
The Stone City Formation is a geologic formation in Texas. It preserves fossils dating back to the Paleogene period. Now known as Stone City Bluff in Burleson County, Texas, it is a special location on the Texas Gulf Coast Plain. It is the best of relatively few places where marine rocks of Paleogene age are exposed and available for public access. This access provides a window into Middle Eocene rocks that were deposited in the Gulf of Mexico approximately 41.8 million years ago.
