Product Information

We believe that giving children the right materials, they will make and play with beautiful things that last a lifetime. When taken together, this alternative explanation suggests that mosasaur teeth developed more like those of other lizards than those of snakes. Feasting on a diverse diet, mosasaurs were apex predators, preying on fish, smaller marine reptiles, and even ammonites and other marine creatures.

I did my Masters degree at the University of Alberta on mosasaurs: giant marine lizards from the Late Cretaceous. Included with all of our fossils is a copy of our ethos, which shows how your investment in our brand is directly helping to protect the environment against habitat destruction and the increasing loss of biodiversity across the globe. v=1638890853","width":1200},{"alt":null,"id":5806635810899,"position":5,"preview_image":{"aspect_ratio":1. Mosasaurus was a prehistoric reptile that swam, having adapted legs into flippers (similar to the evolution of whales).A prehistoric reptile that swam, having adapted legs into flippers (similar to the evolution of whales). In fact, at its core, my entire PhD thesis was based on this question, exploring tooth attachment and tooth development in all kinds of extinct animals, spanning 300 million years of evolutionary history!

Mosasaurs probably evolved from semi-aquatic scaled reptiles which were similar in appearance to modern-day monitor lizards. v=1575217633"}},"requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}},{"id":14724733239331,"title":"Medium 1-1. An artists reconstruction of the Mosasaurus beaugei whose fossils are found in the Late Cretaceous phosphate deposits of Morocco. These reptiles look like an amalgamation of a child’s favorite animals: a whale’s body with the head of a Komodo dragon and the tail of a shark. Although mosasaurs diversified and proliferated at a spectacular rate, their specialization is considered the source of their demise when marine systems collapsed at the end of the Cretaceous.A study done in 2014 on fossilized mosasaur skin shows that the skin was extremely rich in pigment, suggesting that it was at least partially very dark and supporting the countershading claims. Their diet consisted of slow moving animals like ammonites, birds and turtles but they would also tackle larger and swifter prey, such as sharks and plesiosaurs, when the opportunity arose. While this evidence alone suggests the Mosasaurs were formidable predators, a spectacular new find in Jordan has revealed that Mosasaurs were "countershaded" with darker pigmentation on the top and lighter on the bottom.
