Hungry for dino meat: A pointy-tooted mammal that preyed on dinosaurs
Article Abstract:
Newfound fossils revealed a baby dinosaur inside a mammal's gut, which made the first direct evidence of predation. An international team based its conclusions on a mammal species called Repenomamus robustus, which contained the skeleton of a young dinosaur whose serrated teeth, limbs and toes mark it as Psittacosaurus, a hornless relative of Triceratops that reached cow proportions in adulthood.

How dinosaurs grew so large -and so small

The high growth rates of dinosaurs gives an idea about their metabolic features, and the higher the metabolic rate that is the more energy devoted to building up and breaking down bone and other tissues, the faster the tissues would grow.
