We excavated what is most likely a Clidastes Mosasaurus from the Ozan Formation in North Texas. We have several specimens and this Mosasaur has not been prepped and I don't expect to have the time to remove the matrix with an air scribe in the next 10 years as it takes patience and time...so we will list this specimen and more associated vertebrae very soon. The Vertebrae are incased in matrix resembling limestone/chalk. The processes are inside most blocks some broke when using hammer drill on massive 4 foot blocks 30 feet up a wall...literally......see photos for what you will receive. I will try to add more pics of these 3 as well as add more listings shortly.

These fossils are from the Cretaceous Period - The Cretaceous is defined as the period between 145.5 and 65.5 million years ago,* the last period of the Mesozoic Era, following the Jurassic
