Lythronax skeleton among those of other tyrannosaurs

Lythronax is a genus of tyrannosaurid dinosaur that lived in North America around 80.6–79.9 million years ago. Size estimates for Lythronax have ranged between 5 and 8 m (16 and 26 ft) in length, and between 0.5 and 2.5 t (1,100 and 5,500 lb) in weight. It was a heavily built tyrannosaurid; as a member of that group, it would have had small, two-fingered forelimbs, strong hindlimbs, and a very robust skull. The rear part of the skull of Lythronax appears to have been very broad, with eye sockets that faced forwards like those of Tyrannosaurus. Lythronax is the oldest known member of the family Tyrannosauridae, and it is thought to have been more basal than Tyrannosaurus. Due to its age, Lythronax is important for understanding the evolutionary origins of tyrannosaurids, including the development of their anatomical specializations. The forward-facing eyes of Lythronax gave it depth perception, which may have been useful during pursuit predation or ambush predation. (Full article...)

Today's featured picture

Ray Strachey (4 June 1887 – 16 July 1940) was a British feminist politician, mathematician, engineer, artist and writer. For most of her life, Strachey worked for women's suffrage organisations, starting when she was studying mathematics at Cambridge, during which time she took part in the Mud March of February 1907. Her ambition to become an engineer was abandoned when she married Oliver Strachey, a civil servant and cryptographer, in 1911; she continued to take an interest in the role of women in engineering, and campaigned on behalf of the Society of Women Welders in 1920 for women to be permitted to remain in the trade. After World War I, women were granted the vote and permitted to stand for parliament, and she stood as an independent parliamentary candidate in Brentford and Chiswick at the general elections of 1918, 1922 and 1923, without success.
