Juvenile classic dinos found

Adam Khor

It's two separate discoveries; one of them is a juvenile Acrocanthosaurus found in the Cloverly Formation. The study says that Acrocanthosaurus grew at rates similar to Allosaurus and tyrannosaurs, but also that it seemingly reached adulthood in 20 or 30 years (Tyrannosaurus rex at least grew faster then, as it is said that it reached adulthood at around age 18... or that's the last thing I read).

There's also a baby Brachiosaurus measuring only 2 meters long, found in the Morrison formation:

Both are extremely interesting as we know very little about baby dinosaurs- we tend to imagine them as miniatures of their parents yet we know at this point that it wasn´t the case. I only wish they publish reconstructions of the creatures at one point...
