Scientists Discover Last Meal in 75-Year-Old Tyrannosaurus Stomach

The following is the translation of the given 'Bahasa' text to 'English' while preserving any HTML tags: "Scientists have successfully uncovered the last meal of a 75 million-year-old tyrannosaurus. The food turned out to be two baby dinosaurs. This discovery provides new insights into the lives of predators like the tyrannosaurus and their lives millions of years ago."

Dr. Darla Zelenitsky from the University of Calgary stated that this discovery is concrete evidence that tyrannosaurs underwent significant changes in their eating habits as they aged.

This is a young gorgosaurus specimen, a close cousin of the giant tyrannosaurus rex.

When dead, this teenage tyrannosaurus weighed around 330 kg, which is only about ten percent of its fully grown weight. The hind legs of two small bird-like dinosaurs, called citipes, can be seen under its rib bones. Dr. Zelenitsky, one of the main researchers in this study published in the journal Science Advances, stated, "Now we know that this teenage tyrannosaurus did indeed hunt small and young dinosaurs."

Attack and Eat Herbivorous Dinosaurs.

By referring to previous fossil evidence, including bite marks on larger dinosaur bones that match Tyrannosaurus teeth, scientists can imagine a scene when a three-ton adult Gorgosaurus attacks and eats a large herbivorous dinosaur.

Dr. Francois Therrien from the Royal Tyrell Museum of Palaeontology stated that adult tyrannosaurs tend to be relatively non-selective feeders.

Dr. Francois Therrien suggested that adult tyrannosaurs may have attacked large prey using the method of "biting bones and peeling off flesh," he revealed to BBC News.

This fossil was initially discovered in Alberta Badlands in 2009, an area that has become the center of attention for dinosaur fossil hunters.

This fossil is found in rocks and goes through a process of years to reach its current condition. Initially, it is not clearly visible whether there is prey inside its stomach. However, experts at the Royal Tyrell Museum of Palaeontology in Alberta detected the presence of a small toe bone protruding from the rib bone.

Gorgosaurus is a species that is slightly smaller and older compared to T. rex. When they reach adulthood, they become "big and muscular tyrannosaurs."

They undergo physical transformations as they age. Dr. Therrien explains, "Adolescents have lighter bodies, longer legs, and teeth resembling knives." He adds, "In adult individuals, their teeth are much rounder, and we call them 'killer bananas'. The uniqueness of these specimens is physical evidence of significant differences in feeding strategies between the adolescent and adult phases."

"They are not just monsters, but highly skilled creatures in searching for food."
