Discover how Hypacrosaurus growth rate allowed it to evade predators in the Cretaceous with unique defensive strategies. Take Hypacrosaurus. It was one of the duck-billed dinosaurs known as hadrosaurs ...

Dinosaurs—they grow up so fast, especially if they’re trying not to get eaten. Hypacrosaurus, a duck-billed dinosaur that could reach more than 30 feet in length, was a preferred meal of the ...

What some dinosaurs lacked in body armor, they made up for in size. The duck-billed hadrosaur grew to adulthood much faster than its predators, such as tyrannosaurs, a new study suggests. By about age ...

This study is lead by Dr. Alida Bailleul (Institute of Vertebrate Paleontology and Paleoanthropology, the Chinese Academy of Sciences) and Dr. Mary Schweitzer (North Carolina State University, NC ...

Cartilage cells from skull of Hypacrosaurus nestlings. On the left are two cells at the end of cell division, showing material consistent with condensed nuclei. Right in the middle is the higher ...

With long limbs and a soft body, the duck-billed hadrosaur had few defenses against predators such as tyrannosaurs. But new research on the bones of this plant-eating dinosaur suggests that it had at ...

Cartilage cells, chromosomes and DNA have been found preserved in the 75-million-year-old fossils of a baby duck-billed dinosaur, a study has claimed. Researchers analysed the skull fragments of young ...

A good defence was a vital part of life in the Cretaceous. Plant-eaters needed effective ways of warding off the crushing jaws of Tyrannosaurus and its kin. Some species like Triceratops and ...
