In addition to the tyrannosaurs, researchers have also found seven species of turtles, multiple fish and ray species
Ferocious tyrannosaur dinosaurs may not have been solitary predators as long envisioned, but more like social carnivores such as wolves, . Paleontologists developed the theory while studying a mass tyrannosaur death site found seven years ago in the Grand Staircase-Escalante National Monument in southern Utah, one of two monuments that the Biden administration is considering restoring to their full size after former President Donald Trump shrunk them. Using geochemical analysis of the bones and rock, a team of researchers with the University of Arkansas determined that the dinosaurs died and were buried in the same place and were not the result of fossils washing in from multiple areas.![](/newspic/picid-1269750-20250212004700.jpg)

They found the duration of trumpets remained fairly consistent across all age classes for both male and female Asian elephants but roars and roar-rumbles got longer with age.

The STS-63 mission, more popularly dubbed as the near-Mir mission, was a successful mission that spanned from February 3-11, 1995. A mission that served as a dress rehearsal for later missions that would rendezvous and dock with Mir, STS-63 reeled off a number of firsts. A.S.Ganesh tries and lists them out for you…
