Cast of the holotype tooth

Dromaeosauroides was a theropod dinosaur that lived around 140 million years ago during the Early Cretaceous, making it one of the oldest known dromaeosaurs. In 2000 and 2008, two fossilised teeth from this genus (cast pictured) were discovered in the Jydegaard Formation in the Robbedale valley, on the island of Bornholm, Denmark, in the Baltic Sea. It is the first dinosaur reported from Denmark. After these discoveries, remains and tracks of more dinosaurs were found in several formations on Bornholm. Coprolites containing fish remains found in the Jydegaard Formation may belong to Dromaeosauroides. The teeth are curved and finely serrated. Based on a comparison with other dromaeosaur teeth, the genus is estimated to have been 2 to 3 metres (7 to 10 ft) in length, with a weight of about 40 kilograms (88 lb), a hide covered with feathers, and a large sickle claw on both feet. It lived in a coastal lagoon environment with sauropods, as evidenced by a possible titanosaur tooth. (Full article...)

Today's featured picture

A plough is a farm implement that turns over the upper layer of soil, bringing fresh nutrients to the surface as part of preparation for sowing seeds or planting. In early agriculture, soil was turned by hand using digging sticks and hoes. The first animal-drawn plough was the ard, with the earliest evidence of a ploughed field dating to the Indus Valley Civilisation site of Kalibangan from around 2800 B.C. Wheels were introduced by Celtic peoples during the Roman era, and the mouldboard plough, a major innovation in plough technology, was invented in the 18th century. Modern ploughs are usually reversible ploughs, mounted on a tractor.

This painting, Ploughing in the Nivernais, was completed by the French artist Rosa Bonheur in 1849 and is now in the Musée d'Orsay in Paris.
