Dinosaur Fossils be evidence for Omnivorous hunger

Dinosaurs fossils originate in southern Alberta illustrate that some creatures that roamed around the seas 74 million years ago were capable to eat just about something that classify to live on the flourish. A research group improved the leftovers of two prognathodon specimens, frequently described as marine reptiles regarding six-meters long also directly related to lizards, 30 km from southwest of Lethbridge in 2002 and 2007. The recently exposed fossils are supposed to be the world's only fossils of this kind to have been found with both the skulls and skeletons in one piece.

The investigate was lead by Royal Tyrrell along with Takuya Konishi and Donald Brinkman, who considered the dinosaur fossils in an effort to untie a real primitive puzzle. When investigative the sealed guts of the second prognathodon, also element of the mosasaurs family, scientists exposed a large fish about 1.6 meters long, a 60-cm turtle covering and what they describe as a potential ammonite jaw. “What was important was this prognathodon was able of feeding not only on fish, like the majority mosasaurs did, but it might also eat turtles," said Konishi. "That tells us it was capable to piece meat with its teeth and it might also chew hard-shelled animals." Thus the latest finding indicates the prognathodon was "almighty" in its maritime food chain, Konishi also added additionally.

The discovery also help the scientists piece back mutually part of an evolutionary mystery as past research showed that while the prognathodon heads were huge, their torsos proved to be a lot smaller. "Regardless of its huge head, the skeleton was not at all enormous, it was excessively slim," said Konishi. The latest study showed that the mosasaurs' heads were surrounded by the first body parts of the creatures to develop and were adapt so the reptiles might expand their eating habits, mainly improving their continued existence rate, and significant them to prosper at the top of their ecosystem.
