Dr. Elias Root Beadle

Lystrosaurus lived during the Late Permian and Early Triassic Period 255 – 245 million years ago, dying out a few millions of years before the dinosaurs evolved. Dr. Elias Root Beadle, a Philadelphia missionary and avid fossil collector, discovered the first Lystrosaurus skull in 1859.

When was the Lystrosaurus discovered?

Lystrosaurus is an extinct therapsid (mammal-like reptile) which lived approximately 260 million to 240 million years ago – from the Late Permian Period through the Early Triassic Period. The first fossil of this dinosaur was just a skull that was discovered by a missionary named Dr. Elias Root Beadle in 1867.

Who found the first Mosasaurus?

Many complete mosasaur specimens have been found in the Smoky Hill Chalk Member of the Niobrara Formation of Western Kansas, and some of the first mosasaur remains were collected by Professor Benjamin Mudge and Dr. George M. Sternberg more than 130 years ago.

The mosasaurs disappeared from the fossil record alongside non-avian dinosaurs 65.5 million years ago, after a giant asteroid crashed into Earth at the end of the Cretaceous period.

What is the biggest water dinosaur?

If you’ve seen Jurassic World, you know that the fearsome antagonist, a hybrid beast called Indominus Rex, is female. All the dinosaurs are female, we’re told in the Jurassic Park series of movies, to prevent breeding.

Is Mosasaurus still alive?

During the last 20 million years of the Cretaceous period (Turonian–Maastrichtian ages), with the extinction of the ichthyosaurs and pliosaurs, mosasaurs became the dominant marine predators. They became extinct as a result of the K-Pg event at the end of the Cretaceous period, about 66 million years ago.

What’s the spitting dinosaur in Jurassic Park?

How big is a Tylosaurus?

45 feet

Tylosaurus grew more than 45 feet (14 meters) long, making it the largest of the marine reptiles called mosasaurs. Like all mosasaurs, a long and muscular, vertically flattened tail powered Tylosaurus through the water, allowing it to ambush its prey with rapid bursts of acceleration.

How tall is the Tylosaurus?

proriger attained lengths of 13–14 meters (43–46 ft). Commenting on the maximum sizes of large mosasaurs, paleontologist Mike Everhart, a leading expert on mosasaurs, speculated that it would be possible for some extremely old Tylosaurus individuals to reach 20 meters (66 ft) in absolute maximum length.

What era did Tylosaurus live?

Cretaceous period

Related to modern day snakes and monitor lizards, Tylosaurus proriger lived during the Cretaceous period about 85 million years ago.
