酷東西

趣味知識

Baalsaurus is known only from a single right lower jaw bone, called a dentary.2 6

Its jaw was L-shaped when viewed from above, forming a sharp 90-degree angle, which gave it a square snout.2

Baalsaurus had 13 tooth sockets in its jaw, with 10 teeth in the front part and the rest at the corner and side.2

The teeth were pencil-shaped, like other titanosaur sauropods, and each socket had room for at least three replacement teeth growing underneath.2

Scientists estimate Baalsaurus had a skull about 40 centimeters (16 inches) long, based on comparisons with similar dinosaurs like Bonitasaura.2

It lived during the Late Cretaceous period, about 91 to 88 million years ago, in what is now Patagonia, Argentina.1 2
