In Northern Ireland, paleontologists have found dinosaur remains for the first time, Irish and English paleontologists report. These are two bones, each from a different animal, found on the Islandmagee peninsula in Northern Ireland. The fossils are about 200 million years old, from the Jurassic.
Ireland, according to the scientists involved, consists of rocks that do not come from the dinosaur age. The rocks are either too old or too young, making it difficult to find evidence for Irish dinosaurs.
The dinosaur remains found may have come from animals that were dragged into the sea, eventually descended to the seabed and fossilized there.
At first it was thought that ancient bones were once part of the same dinosaur, but now it appears that they come from two separate species. One bone is the thigh of a four-legged herbivore, the Scelidosaurus. The other bone is the lower leg of a two-legged carnivore, Sarcosaurus.
The herbivore’s bone was very dense and robust, which the researchers say is typical of herbivorous armored dinosaurs. The carnivore’s bone was slimmer and with a thinner outer layer, which is typical of fast-moving carnivores.
