Dinosaur Fossils

Bones of juvenile long-necked sauropod dinosaurs, Abydosaurus mcintoshi,

have recently been found in 105-million-year-old sandstone at the Dinosaur National

Monument in Utah. The remains of four individual dinosaurs were found, including

two intact skulls. This find is unusual because the softer tissue holding the thin

sauropod dinosaur skull bones together usually disintegrates, allowing the skull bones

to separate. Only 8 of 120 types of sauropods discovered have complete skull

specimens. These dinosaurs were herbivores, with large numbers of sharp teeth that

were probably replaced five to six times each year. These teeth allowed only for the

harvesting of plant material, but not for chewing it afterward. The plant-harvesting

teeth and long neck identify Abydosaurus mcintoshi as a descendant of the

brachiosaurs.

mcintoshi lived. [
