酷東西

趣味知識

Owenodon is known mostly from a partial lower jaw with ten teeth, found in a limestone block.1

It was first named Iguanodon hoggii by Richard Owen in 1874, honoring naturalist A.J. Hogg who collected the fossil.1

The jaw was damaged while stored in a museum collection, breaking one tooth crown and part of the bone.1

Owenodon lived in a warm, Mediterranean-like climate with lakes, lagoons, and salty marshes.1

Scientists think Owenodon was an intermediate ornithopod, between Camptosaurus and Iguanodon in evolution.1

The only definite fossil of Owenodon comes from the Lulworth Formation in Dorset, which is about 140 million years old.1 3

發現: The fossil was discovered by A.J. Hogg in the Purbeck Limestone of Dorset, England, and described by Richard Owen in 1874 as Iguanodon hoggii. It was given its own genus Owenodon by Peter Galton in 2009.1
仍有爭議: Scientists are not sure exactly where Owenodon fits in the ornithopod family tree, because the fossils are so few and incomplete.1
