Fatgs divertents

Tenontosaurus had an unusually long and broad tail, stiffened by a network of bony tendons, which is why it is called 'sinew lizard'.1

An adult Tenontosaurus could reach a browsing height of about 3 meters (10 feet) if it stood on its hind legs, but it usually walked on all fours.1

Its beak was U-shaped and thick, and its lower jaw had a special bone called a predentary that helped form the lower beak.1

Tenontosaurus lived alongside the predator Deinonychus, and fossils of both are common in the same rocks.1

The first Tenontosaurus fossil was found in 1903 in Montana, but it was not named until 1970.1

There are two species: Tenontosaurus tilletti and Tenontosaurus dossi. T. dossi is known from only a few specimens in Texas.1

?Why did Tenontosaurus have a long tail?

Its tail was unusually long and broad, stiffened by bony tendons. This helped support the tail, but scientists aren't sure of its exact purpose.1
