The Oldest Super Predator Living on Earth, Tyrant Swimmer Discovered by the Scientists

Jan 9, 2013 12:35 IST

Scientists at the University of Edinburgh's School of Biological Sciences in the second week of January 2013 discovered that the oldest known super predator of the world was the marine crocodile. Predators are the carnivores that are capable of feeding on the prey which is large or even larger than them.

This recently discovered oldest known super predator of the world, a marine crocodile was a toothy beast which looked partly like a shark and partly like a threatening dolphin. The scientific name of this oldest predator of the world is Tyrannoneustes lythrodectikos or simply Tyrant Swimmer.

The lead author of the University of Edinburgh's School of Biological Sciences, Mark Young described that the Tyrant Swimmer was the oldest metriorhynchid macrophage, an animal with a capability of feeding on the large-bodied prey. The term called metriorhynchid basically represents the bunch of marine crocodiles which were identical to dolphins that we see now. However, they do not have bony armour, but do have tail fluke and flipper-like forelimbs. Tyrant Swimmer was capable of opening its mouth wider.

The remains of the Tyrant Swimmer which were found in Oxford Clay Formation, the Jurassic marine sedimentary rock formation originally from Southeast England were studied. These remains were stored for sometime at Hunterian Museum in Glasgow.

Tyrant Swimmer basically is known to be from the shallow marine areas across Europe, primarily Poland, England and France. Around 165 million years ago, a lot of Europe was completed covered by the shallow sea, which also led to the formation of large to small islands. It is in this shallow sea that the Tyrant Swimmer lived with various other marine reptiles.

However, the Tyrant Swimmer might have been faster in water than others, which allowed it to out-swim possible predators. Tyrant Swimmer could have used its swimming capabilities for capturing the prey.

However, no contents of the stomach of Tyrant Swimmer were located as of now, which meant that what it ate precisely, is still a mystery.
