Here's my finished Spinosaurus painting for the end of the year based on Scott Hartman's skeleton drawing. A Spinosaurus, with long narrow jaws with conical teeth and a unique tail for aquatic locomotion, is seen in an illustration provided April 29, 2020. Described early in 2020, the tail of Spinosaurus was long, thick and eel-like - no other known dinosaur had one like this. The biggest carnivorous dinosaurs of all time, Spinosaurus aegypticus (spined lizard), commonly called the Spino, is a top pick for people that just want to be a large carnivore. In 1912, Richard Markgraf discovered a partial skeleton of a dinosaur in the Bahariya Formation of western Egypt.
