PARIS, FRANCE 鈥 An ancient relative of the giraffe was a huge, heavy animal with thick legs, a flat face and massive, curly horns flaring out from its skull, said a study on Wednesday.

The reconstruction of a skeleton of an extinct giraffe-like animal, assumed to be the biggest ruminant mammal ever —

Dubbed Sivatherium giganteum, the impressive creature would have been shorter than today鈥檚 giraffe, with a less elongated neck, a trio of British scientists wrote in the Royal Society journal Biology Letters.

Using bones dug up in India in the 1830s and now in London鈥檚 Natural History Museum, the team built a computerized 3-D reconstruction of an animal they said would have stood about 1.8 meters (5.9 feet) tall at the shoulder and weighed about 1.2 tons.

鈥淭his was a heavy animal with thick legs,鈥 co-author Christopher Basu told AFP by e-mail.

Added to the large, flattened horns or 鈥渙ssicones鈥 on the top of the skull, each about 70 centimeters (28 inches) long, it also had two smaller, pointy horns just over the eyes.

鈥淚t would have been an impressive and strong animal,鈥 said Mr. Basu. 鈥淚t鈥檚 face would have looked very different from a giraffe. Giraffe鈥檚 have very long, pointed skulls. Sivatherium had a very short, flattened skull.鈥

It lived somewhere between the last five million and 12,000 years ago.

Related to the giraffe and its cousin the okapi, Sivatherium was possibly the largest ruminant animal 鈥 those with multi-compartmented stomachs 鈥 to ever have lived.

The first scientists to study Sivatherium bones misclassified the animal as an archaic link between modern ruminants and a long-extinct relative of elephants and rhinoceroses.

For the new study, the skeleton was reconstructed using 26 fossil bones from three individual animals. The ribs, back and pelvis are missing.

鈥淲e estimated what these might look like from giraffe and okapi anatomy 鈥 the two living relatives,鈥 said Mr. Basu. 鈥 AFP
