Cat-Sized T. rex Babies Were Quick to Hunt, Study Finds

A Biology (2026) study of tyrannosaurid hatchlings, including T. rex and Gorgosaurus libratus, shows newborns weighed about 2.5 kg (cat-sized) but grew rapidly, with vascularized bones and tooth wear suggesting early hunting. CT scans indicate these young dinosaurs left the nest quickly, likely hunted soon after hatching, and the brood may have comprised 20–30 eggs, implying a strategy of many small young with relatively light parental investment.

Baby Dinosaur Fossils Reveal Early Armor in Some Species

New research confirms that tiny fossils of Liaoningosaurus paradoxus are of baby ankylosaurs, not miniature adults, providing rare insights into early armor development and growth in armored dinosaurs, including the discovery of the first hatchling ankylosaur.

Tyrannosaur's Last Meal: A Rare Glimpse into its Diet

Scientists have discovered the last meal of a 75-million-year-old tyrannosaur, revealing that it had consumed two baby dinosaurs. The fossil, belonging to a juvenile gorgosaurus, provides solid evidence that tyrannosaurs changed their diet as they grew. While adult tyrannosaurs were indiscriminate eaters, hunting large plant-eating dinosaurs, the juvenile gorgosaurus hunted small, young dinosaurs. The fossil also highlights the different feeding strategies between juveniles and adults, with the juvenile gorgosaurus selectively dissecting its prey. This finding sheds new light on the predatory behavior and development of tyrannosaurs.
