This specimen had a skull of exclusively 4 centimeters. MD Federico Agnolin, researcher at the Argentine Museum of Natural Sciences (MACN) together with CONICET, told the CTyS-UNLaM Agency that "this novel species is an ancestor, a form of granddaddy of the dinosaurs and, yesteryear the shape of its teeth, nosotros interpreted that it fed on insects that it captured nimbly amid the ancient Texan forests ".

"The skull of the Soumyasaurus has many features that makes us intend of the electrical flow birds, piece nosotros were able to recognize that it had a real abrupt ear together with a spectacular vision," said the Argentinean researcher who carried out this interrogation together amongst the specialists Volkan Sarıgül together with Sankar Chatterjee of the Texas Museum.
Because of these characteristics, specialists believe that it could bring been a nocturnal animal. Their fossils were works life inwards the Post-Quarry field, inwards western Texas, inwards 1993. However, due to the same characteristics of the specimen, the enigmas of this novel species bring non been interpreted or solved until today.
"Although the size of the Soumyasaurus aenigmaticus did non transcend one-half a meter, it was an agile together with intelligent animal," Agnolin said. And together with thus he analyzed: "Possibly, these characteristics allowed this species together with its relatives to live real successful together with capable of escaping from the jaws of the enormous reptiles amongst which they lived".
The Soumyasaurus is an ancestor of the showtime dinosaurs. It also has features like to electrical flow birds, that is to say, has similarities amongst modern dinosaurs that managed to locomote the extinction that occurred 65 1000000 years ago.
Also, inwards this site inwards Texas, a vertebral column together with fragmentary remains of other saurians were works life that are described inwards this written report published inwards the Natural History magazine of the Félix de Azara Foundation.
During almost all the Triassic menses that extended until the 200 1000000 years, the dinosaurs had sizes non real greater to those of a Canis familiaris or a sheep. Recently, a few months ago, researchers from the Institute together with Museum of Natural Sciences of the University of San Juan (IMCN) unveiled the showtime illustration of gigantism amid dinosaurs, from an plant eater species most 208 1000000 years old. which they baptized every bit Ingentia prima.
However, this illustration is an exception to the size of the dinosaurs at that time. And the characteristics observed inwards the Soumyasarus would bring been decisive for the dinosaurs, finally, managed to dominate the populace for the side yesteryear side 180 1000000 years.
At the fourth dimension of Soumyasaurus aenigmaticus, the continents were united forming a huge continental majority known every bit Pangea together with at that spot were withal no flowering plants, grasses or weeds, thus it is estimated that the Triassic populace did non bring many colors.
Pangea contained swell deserts inwards its interior together with because it was fragmented yesteryear oceans, the animals could live distributed from 1 side of the globe to the other. That is why like animals are works life inwards distant points of the Planet for that time.
