När levde Mosasaurus?
Fossil daterade till cirka 85 milj. år sedan visar en påfallande storlek jämfört med tidigare släktingar, såsom Mosasaurus, som tros ha varit omkring 13 meter lång, Prognathodon, cirka 9 meter, och Tylosaurus, cirka 12 meter.
Var levde Mosasaurus?
Mosasaurus levde en gång i det stora innanhavet i Nordamerika.
Vad åt Mosasaurus?
Experter tror att Mosasaurus levde nära ytan där den jagade fisk, sköldpaddor, ammoniter, mindre mosasaurier och plesiosaurier. Inga fossil har hittats som skulle tyda på att de dök till djupa vatten och deras anpassningar tyder på en mer ”ytlig” diet.
What is a mosasaur?
Mosasaurs are a large diverse group of mostly marine reptiles that lived from the mid to the late Cretaceous period. They evolved from small lizard-like squamates like Aigialosaurus.
Was Mosasaurus a predator or prey?
Paleontologists generally agree that Mosasaurus was likely an active predator of a variety of marine animals. Fauna likely preyed upon by the genus include bony fish, sharks, cephalopods, birds, and marine reptiles such as other mosasaurs and turtles. It is unlikely Mosasaurus was a scavenger as it had a poor sense of smell.
What did mosasaurs eat?
Mosasaurs did not usually eat this type of prey. Instead they had sharp, serrated teeth for cutting into prey and tearing them up. Mosasaurs have been found with lots of different sea animal fossils in them. This includes sea-birds, sharks, ichthyosaurs, plesiosaurs and even dinosaurs and other mosasaurs.
