The juvenile tyrannosaurus rex most popular dino drumsticks over wings.
That’s the unprecedented willpower of Alberta paleontologists after analyzing the abdomen contents of the fossilized creature unearthed in 2009 within the Dinosaur Provincial Park badlands close to Brooks.

“After they collected it, they didn’t understand there was something within the abdomen,” stated Dr. Darla Zelenitsky, affiliate professor within the Division of Earth, Power and Atmosphere on the College of Calgary.

“It wasn’t till they cleaned up the fossil that they discovered toe bones protruding.”
What the researchers on the Royal Tyrrell Museum discovered whereas chipping away on the fossilized gorgosaurus, a species of T. rex, have been the legs of a pair of small, birdlike dinosaurs often known as citipes elegans lodged in its abdomen.
It’s a discovery that’s excited the world paleontology neighborhood, say native researchers.
“It’s the primary (such discovery) in any tyrannosaur and the primary good indication of the weight-reduction plan of a juvenile — we might solely hypothesize earlier than what they have been consuming,” stated Zelenitsky of the discover made by Royal Tyrrell technician Darren Tanke.
“It appears to be a very fussy eater.”
The superb preservation of the T-rex and its abdomen contents was probably the results of the meat eater being swept away by a river and entombed in sand 75 million years in the past, she stated.
That protected it from decomposition and hungry predators, say paleontologists.
“It’s fairly superb — the one factor that’s actually lacking on it’s the tail,” stated Zelenitsky.
Its prey — a pair of citipes akin to miniature emus or ostriches — was really two meals, given certainly one of them was extra absolutely digested than the opposite, stated Zelenitsky.

And it illustrates how the dinosaurs’ victims grew together with the scale of the meat eaters’ our bodies, noting the juvenile gorgosaurus aged between 5 and 7 years would have weighed 335 kilograms, or solely 10 per cent of a completely developed grownup.
Grown-up T. rexs consumed dinosaurs typically bigger than themselves, stated the researchers.
“You continue to wouldn’t need to run into (a juvenile) — they have been agile and quick runners in a position to chase down these little dinosaurs,” stated Zelenitsky.
A paper produced by the findings has been revealed within the journal Scientific Advances.
The fossil now resides on the Royal Tyrrell Museum in Drumheller, about 140 kilometres northwest of the place it was discovered.
Fossil might be placed on show at Royal Tyrrell Museum after extra research
It’s the museum’s hope to position the fossil on show however researchers aren’t but completed learning it, stated Royal Tyrrell paleontologist Dr. Francois Therrien.
“We nonetheless need to be taught extra in regards to the prey. They’re very poorly identified and these are probably the most advanced skeletons as a result of they have been preserved within the abdomen of the tyrannosaur,” he stated.

It’s taken 14 years because the fossil’s unearthing to announce the discovering as a result of harm accomplished by the gorgosaurus’s acidic digestive system and the challenges of figuring out its dinner, stated Therrien.
It’s a discover that additionally exhibits how the juvenile T. rex, by specializing in the legs of its victims, was a extra surgical eater than its grownup counterparts, stated Therrien.
“The meatier half was actually the legs,” he stated.
The badlands round Drumheller showcase fossils a number of million years youthful than these discovered within the Brooks space, stated Zelenitsky.
“You’ve a special ecosystem at Dinosaur Provincial Park in comparison with Drumheller,” she stated.
The richest dinosaur fossil beds in Canada are these a half-hour drive northeast of Brooks, which have been yielding specimens because the late 1800s and stay an interesting supply, stated Therrien.
“There are nonetheless discoveries to be made in Alberta for years to come back,” he stated.
Dinosaur Provincial Park’s fossil treasures have earned it a UNESCO World Heritage Website designation.
