Coprolite is the fossilised excrement of reptiles (dinosaur dung, so to speak). They occur in the form of nodules and contain a lot of phosphatic material. The term has come to apply to any phosphatic nodule.

Abelisaurus is a dinosaur about which very little is known. An almost complete skull, measuring 85 cm long, was discovered in Argentina in 1985, and this indicates that it was a carnivore of the cretaceous period.

Acanthopholis was a dinosaur of the Cretaceous period, remains of which were first discovered in 1865 at a beach near Folkestone, England by Professor T H Huxley. Acanthopholis measured about 5.5 metres in length and is believed to have been protected by armour consisting of rows of oval plates set in the skin and sharp spikes along the middle of its back.

Alamosaurus was 21 metres long, walked on four legs and had a long neck and tail.

Albertosaurus was a dinosaur from the late Cretaceous period, remains of which were first found in 1905 in the USA. A carnivore. Albertosaurus walked on its hind legs and had small, relatively poorly formed forward legs. In 1923a skeleton of a juvenile Albertosaurus was discovered and at the time identified as a distinct species and given the name Gorgosaurus, however it was later found that the animal grew heavier and stronger as it aged, and the skeleton was that of an Albertosaurus.

Allosaurus was the biggest and fiercest carnivorous dinosaur of the Jurassic period. It was 15m tall, about 12 m long and weighed about three tons. Remains of Allosaurus were first discovered in Colorado in 1869 and then in 1877 more were discovered by Dr O C Marsh.

Anatosaurus was an amphibian, webbed-hand dinosaur of the Cretaceous period, remains of which were first found in 1942. Anatosaurus was a herbivore, and from extensive remains found including mummified samples with skin connected, we know that it was between 10 and 13 metres long, walked on its hind legs and had forelegs adapted a little like hands, the fingers of which were covered in a webbed skin, presumably to assist in swimming. Anatosaurus had a low, broad skull with a snout similar to a duck's.

Anchiceratops was a dinosaur of the Cretaceous period. A herbivore,
Anchiceratops was about 5 or 6 metres long with long horns protruding forward above its eyes and a long neck-frill with knobs and spines pointing backwards. Remains of Anchiceratops were first discovered in 1914.
