Paleontologist Alan Titus, who discovered the Rainbows and Unicorns site in 2014 and is one of the lead authors of the
PeerJ study, says that the group of deceased and fossilized Tyrannosaurus rex specimens were the victims of a massive flood that drowned them and washed their bodies into a lake. They lay on the bottom, grouped together and undisturbed, for millions of years, until climatological and geological changes dried the lake and created a river (also now gone) that eroded the soil and brought the bones back up to the earth’s surface.
“We used a truly multi-disciplinary approach (physical and chemical evidence) to piece the history of the site together,” explained Celina Suarez , a University of Arkansas geologist and study participant. “The end-result [was] that the tyrannosaurs died together during a seasonal flooding event.”
Fossils found in Utah indicate tyrannosaurs were social predators, not solitary
New research from paleontologists in Utah found evidence that tyrannosaurs may have been social, rather than solitary as previously believed.

KANAB, Utah â New research from paleontologists in Utah found evidence that tyrannosaurs may have been social â hunting in packs like wolves â rather than solitary as previously believed.
In 2014, Dr. Alan Titus of the Bureau of Land Management (BLM) discovered what was later named the Rainbows and Unicorns Quarry site in Grand Staircase Escalante National Monument.
Scientists discovered a tyrannosaur mass death site there â the first of its kind to be found in the southern United States, according to a press release from the BLM.
Tyrannosaurus rex the tyrant lizard king may not have been a solitary predator, but instead hunted its prey in packs, just like wolves, a study has suggested.
Palaeontologists have been studying a T. rex mass death site found back in 2014 in the Grand Staircase-Escalante National Monument in southern Utah.
Analysis of the fossil bones and the surrounding rock has revealed that the dinosaurs died and were buried together, rather than being washed in from other places.
