Turtles, not birds, have been found to be the closest relatives of crocodiles and alligators, according to an analysis of the largest available collection of reptile genes. “The results provide strong evidence that the turtle is the crocodile’s closest living relative,” Hedges concludes.

What is the difference between dinosaurs and crocodiles and lizards?

The answer is simple – dinosaurs have upright legs while crocodiles and lizards have splayed legs. The reptiles also managed to reach for the sky in the form of pterosaurs.However, their fossils are very rare along the Jurassic Coast, partly because the bones were too fragile for fossilisation.

Did crocodiles and turtles ever swim alongside dinosaurs?

A near-complete pterosaur, called Dimorphodon was found by the famous Lyme Regis fossil collector, Mary Anning, in 1824. It’s staggering to think that crocodiles and turtles once walked and swam alongside the dinosaurs.

Why are dinosaur fossils on the Jurassic Coast so rare?

Dinosaur fossils on the Jurassic Coast are rare. Why? Because when dinosaurs were around (in the late Triassic, Jurassic and Cretaceous periods), most of the rocks of the Jurassic Coast were under the sea. So finds usually consist of fragments of dinosaurs that had died, been washed into the sea, then scavenged before becoming fossilised.

What can fossil Poo tell us about dinosaurs?

Fossil poo (coprolites) can tell us a lot about what these animals ate. They are packed with undigested food remains such as fish scales and sometimes the bones of other marine reptiles. Dinosaur fossils on the Jurassic Coast are rare. Why?
