In Nevada, the remains of a pregnant dinosaur that lived 246 million years ago were found. A find made in the Augusta Mountains by a group of scientists led by Martin Sander is described at Phys.org.
The remains were discovered in northern Nevada, 241 km east of the city of Reno. They were located on the slope of one of the Augusta mountains at an altitude of about 1.82 thousand meters.
Researchers found an ichthyosaur spine with a characteristic bend that indicates that the animal in the ocean was pregnant at the time of death.
The found remains do not correspond to any of the ichthyosaurs known to science – on the basis of this, scientists concluded that the animal to which they belonged belongs to a previously unknown species of ichthyosaurs.
Scientists estimated the age of the lizard at 246 million years – this is the second place among the most ancient ichthyosaurs, the remains of which were found. The first belongs to the lizard, who died in modern China about 249 million years ago.
