Jurassic crocodile identified 250 years after find


This video says about itself:

Meet the top 10 largest crocodiles in the world and history. These prehistoric crocodiles are really gigantic, you won’t believe they really existed.

Purussaurus
This is an extinct giant which lived in South America in the Miocene. A 4.7 feet long skull was found in Brazil, that’s why it’s estimated that this species measured 41 feet long and weighed 8.4 tons, making this one of the biggest crocodiles in history.

Mourasuchus
This extinct crocodile lived in the Miocene and its fossils were found in Peru. It’s thought that it measured 30 feet in length.

Smilosuchus
It’s also an extinct specimen that lived in the late stage of the Triassic period in north America.

Deinosuchus
It was an extinct species that could reach 39 feet in length and weight 8.5 tons.

Sarcosuchus
This species reached between 36 and 39 feet in length, because of this size it received the name of Super Croc, with which it has become famous.

Rhamphosuchus
This crocodile used to live in the Ganges river, in India, during the Miocene.

Gryposuchus
This extinct crocodile lived in south America between 23 million and 700 thousand years ago, in the Miocene, Pliocene and beginnings of the Pleistocene.

Stomatosuchus
It was a 32.8 feet crocodile that lived in the late Cretaceous in Egypt. It had a plain head seen from the top that looks a lot like a cricket bat.

Rutiodon
Was a reptile genre that lived at the end of the Triassic period, its name means creased tooth. It measured 26 feet in length and its fossils have been found in the eastern part of the United States.

Machimosaurus
This prehistoric crocodile specimen reached the length of 23.6 feet. It lived in the late Jurassic and early Cretaceous era, which means this was contemporaneous to the dinosaurs.

Mysterious Jurassic crocodile identified 250 years after fossil find

September 12, 2019

Summary:.A prehistoric crocodile that lived around 180 million years ago has been identified — almost 250 years after the discovery of its fossil remains.

A fossil skull found in a Bavarian town in the 1770s has been recognised as the now-extinct species Mystriosaurus laurillardi, which lived in tropical waters during the Jurassic Period.

For the past 60 years, it was thought the animal was part of a similar species, known as Steneosaurus bollensis, which existed around the same time, researchers say.

Palaeontologists identified the animal by analysing fossils unearthed in the UK and Germany.

The team, which included scientists from the University of Edinburgh, also revealed that another skull, discovered in Yorkshire in the 1800s, belongs to Mystriosaurus laurillardi.

The marine predator — which was more than four metres in length — had a long snout and pointed teeth, and preyed on fish, the team says. It lived in warm seas alongside other animals including ammonites and large marine reptiles, called ichthyosaurs.

The discovery of fossils in present-day Germany and the UK shows that the species could easily swim between islands, much like modern saltwater crocodiles, researchers say.

The study, led by Naturkunde-Museum Bielefeld in Germany, is published in the journal Acta Palaeontologica Polonica. It was supported by the Palaeontographical Society, Leverhulme Trust and the Natural Sciences and Engineering Research Council of Canada.

Sven Sachs, of the Naturkunde-Museum Bielefeld, who led the study, said: “Mystriosaurus looked like a gharial but it had a shorter snout with its nasal opening facing forwards, whereas in nearly all other fossil and living crocodiles the nasal opening is placed on top of the snout.”

Dr Mark Young, of the University of Edinburgh’s School of GeoSciences, who was involved in the study, said: “Unravelling the complex history and anatomy of fossils like Mystriosaurus is necessary if we are to understand the diversification of crocodiles during the Jurassic. Their rapid increase in biodiversity between 200 and 180 million years ago is still poorly understood.”
