Very nice Tethysaurus nopcsai jaw with all the original teeth from the cretaceous.These fearsome predators once realmed the ancient seas. With a diet consisting out of anything meat like they were once the most fearsome predator alive. It's the first and oldest species of Mosasauridae that ever existed.This jaw is from an adult animal and was found in 2011 in Goulmima.The only layers where they are found are known to have a rather large proportion of distortions, what is not the case here. Preserved perfect anatomically correct.100% natural. Great item in any collection.ped by registered and insured mail.
