It is an omnivore – in other words it ate everything (plants and meat) – which is the missing link between carnivorous dinosaurs and giant four-footed herbivores
LiveScience.com – Remains of embryos entombed in their fish mothers’ wombs for 380 million years have been found in fossils from an ancient rock outcrop in Western Australia. The finding is a big deal because it suggests that sex goes way back.
The prehistoric fish, called placoderms, are found at the base of the vertebrate evolutionary tree (in a large group we humans also belong to), so it now looks like sexual intercourse, and the mating behaviors that go along with it, were more widespread in these ancient animals than previously thought, said the scientists who made the discovery. …
In just four years one palaeontologist has discovered 48 new species from the age of the dinosaurs using a systematic search method. The new discoveries, found hidden in mud on the Isle of Wight, are around 130 million years old and shed valuable light on the poorly understood world in which well known dinosaurs roamed.
