A crew from Naturalis Biodiversity Middle within the Netherlands was searching for a Tyrannosaurus in the summertime of 2013 in Wyoming. As an alternative, they discovered a Triceratops: the well-known dinosaur with the three horns and the massive neck frill. After which they discovered one other one. And one other one. And extra. The dig was a undertaking that might final for greater than 10 years.
All in all, they dug up 1,200 bones and bone fragments, of at the least 5 people. A crew {of professional} and volunteer paleontologists and technicians spent years eradicating them from the quarry.
A researcher was employed to check the fossils: how did these useless dinosaurs find yourself there, collectively? What do their bones inform us of their lives and their deaths?
“The fabric is of superb high quality,” De Rooij displays on the dino detective story that’s his Ph.D. thesis. “This enabled us to indicate that these triceratops grew actually slowly, as an example.” The main points of the bonebed point out that the 5 dinosaurs died collectively, presumably mired in a swamp. They’re in a skinny layer of rock, with out bones of different species.

Analysis into the bodily and chemical properties of the tons of of triceratops tooth tells of a migratory existence—one which was the identical for all 5 of the dinos. In different phrases: this species of dinosaur teamed up, at the least sometimes. “And that in fact results in every kind of recent questions,” De Rooij says, “How complicated was this social habits, precisely?”
De Rooij’s supervisor, Prof. Anne Schulp (Naturalis/Utrecht College), could be very comfortable about all the trajectory from dig to protection ceremony.
“Naturalis, the nationwide pure historical past museum of the Netherlands, now has the largest triceratops discover on the earth, and Utrecht College has the primary Dr. Triceratops within the Netherlands. De Rooij’s work did not simply end in analysis papers, but in addition in an exhibition about his findings. As of October, the exhibition will kick off at Naturalis—and kick off the world tour—the place the 5 triceratops are proven as they lived and died 67 million years in the past: collectively.”
