Paleontologists discover dinosaur which lost pearly whites while juvenile and evolved beak in matured phase

In a major breakthrough, a group of paleontologists has discovered the remnant of the vanished dinosaur which has come up with great possibilities of exploring the hidden mysteries of this giant species. In a fossil first, a team of paleontologists has unearthed a fossil of a dinosaur which indicated that there was one species of dinosaur which sued to carry multiple resemblances to the modern birds. The discovery has potentially revealed that the modern birds born with a full set of chompers, but loses them all after getting matured. On behalf of pearly white teeth, the adult birds developed a beak instead.

The discovered fossil is related to the dinosaur species of L. inextricabilis which sued to live on the earth 160 million years ago. To recall, L. inextricabilis was long-established dinosaur species which belonged to the theropod group, a group which members were believed to be ancestrally carnivores. This group is also called the precursor to the modern birds.

On the basis of experiments of 19 specimens, ranging from juveniles to adults, the paleontologists at the George Washington University found the fossil of this eccentric and small dinosaur in the far western Gobi Desert of China. The paleontologists, in the desert of China discovered that L. inextricabilis used to start its life as a carnivore, with an oral cavity containing up to 18 small and sharp teeth, each lengthening a few millimeters. But during the process of growing from a juvenile to adult, the species lost all of their teeth and instead developed a toothless beak which in other ways made them follow a transitioned to a herbivore diet.

The scientists also revealed that the body of this dinosaur was a bit similar to the body of an ostrich, having small arms that wrecked in scrambled fingers, alongside a long tail. At the time of birth, the species was used to be only one foot long while the adults went up to about 8 feet. However, the major difference, the scientists found is the shape and configuration of oral cavity which a juvenile used to have but the mature Limusaurus inextricabilis didn’t.

The lead author of the study is Josef Stiegler, a doctoral student of biological sciences at the George Washington University (GWU).
