Fossil Auktion (Dinosaurer & Reptiler)

Smukt mosasaur-tand fra Marokko, med en velbevaret rod og en del af underkæbebenet. Knoglen er delvist restaureret, men den naturlige porøsitet er stadig tydeligt synlig. Det blev opdaget i det nordvestlige Sahara-område.
Denne kridttids marine reptil var en af de største rovdyr i sin tid. Mosasaurus var blandt de sidste mosasaurer og også en af de største. Ligesom de fleste mosasaurer var lemmerne udviklet til korte men effektive finner, hvor forbenene var større end bagbenene. Den største kendte art, Mosasaurus hoffmannii, kunne nå en længde af 17–18 meter (56 fod), lidt længere end nære slægtninge som Tylosaurus og Hainosaurus.
Mosasaurus var også en af de mest robuste mosasaurer, hvor større individer estimeres at veje mellem 25 og 30 tons. Dens krop var lang, tyk og tønneformet, med et massivt kranie og en kraftig kæbe, tæt forbundet til kraniet. Øjnene var relativt store, men sandsynligvis med begrænset stereoskopisk syn, og lugteorganerne var ikke særligt udviklede, hvilket tyder på, at den levede primært tæt på vandets overflade.

Beautiful Mosasaurus tooth from Morocco, featuring a well-preserved root and part of the mandibular bone. The bone has been partially restored, but the natural porosity is still clearly visible. It was discovered in the northwestern Sahara region.
This Cretaceous marine reptile was one of the largest predators of its time. Mosasaurus was among the last mosasaurs and also one of the largest. Like most mosasaurs, its limbs had evolved into short but efficient flippers, with the front flippers larger than the rear ones. The largest known species, Mosasaurus hoffmannii, could reach lengths of 17–18 meters (56 feet), slightly longer than close relatives such as Tylosaurus and Hainosaurus.
Mosasaurus was also one of the most robust mosasaurs, with large individuals estimated to weigh between 25 and 30 tons. Its body was long, thick, and barrel-shaped, with a massive skull and a powerful jaw tightly connected to the cranium. The eyes were relatively large but likely provided limited binocular vision, and the olfactory bulbs were not well developed, suggesting it lived primarily near the water’s surface.
