Medicine & TechnologyScientists discovered fossils of an armless dinosaur that likely roamed Argentina 70 million years ago and is believed to belong to abelisaurs, a dinosaur with short front limbs.
If, through some scientific malfunction, you found yourself transported 70 million years into the past, you might be safer from certain hungry reptiles than you think.
Research shows that megatheropods or large bipedal carnivores during the Mesozoic era dominated their ecological community by competing with other smaller species, resulting in the lack of species diversity.
One of the most complete specimens of a t-rex fossil of the world was sold in a New York auction at $31.8 million on Tuesday which is four times the price of the previous highest price for a dinosaur.
British auction house Christie's will be auctioning off one of the most complete Tyrannosaurus rex skeletons ever discovered, expecting to fetch a record-setting price on October 6.
In the world of dinosaurs, not everything was as it seems. The most advantageous appendages may have just been for show-and-tell, to ward off unassuming predators, and some of the most evolutionarily superb tricks may never be revealed in the fossils we find today. And with the endless wonder of discovering an entirely unique world, unlike our own, paleontologists, like children, keep learning in the hopes of one day adding their own discovery into the dialogue. The only difference is that one of these differences was recently discovered in a new species of dinosaur related to the Tyrannosaurus rex, but this discovery really was made by a child—seven-year-old Diego Suárez.
