Description: A pair of Allosaurus search for dinner in the pre-twilight of a lush mountainside forest. The orange horns on the foreground Allosaurus identifies this as an adult male, while his female companion behind attempts to make a meal of an unfortunate terrapin. 150 million years ago during the late Jurassic period, giant Sequoias, also known as Redwoods, may have populated all of the northern continents. These evergreens grow as tall as 370 feet and some have trunk diameters exceeding 25 feet. The only living Sequoias today, and some are over 2,000 years old, occupy a narrow strip of land along the North American Pacific coast. Some Allosaurus likely hunted in the shade of Sequoias. For 5 million years Allosaurus was the most common large carnivore in North America. Growing as long as 40 feet and weighing up to two tons, this fierce predator probably had few, if any rivals.
