酷東西

趣味知識

The name Becklespinax honors Samuel Husbands Beckles, who discovered the fossils in the 1850s.2

Its back vertebrae have spines about 35 centimeters (14 inches) tall, as tall as those of some other dinosaurs like Ichthyovenator.2

The three back vertebrae are fused together at the top of the spines, which is unusual.2

Becklespinax lived about 140 to 132 million years ago during the Early Cretaceous.2 1

The famous Megalosaurus sculpture in Crystal Palace Park, London, was given a hump because of these fossils.2

Scientists are not sure exactly which group of theropods Becklespinax belongs to, so they call it Tetanurae incertae sedis (uncertain placement).2

迷思破解王

迷思： Some people think Becklespinax is the same as Altispinax or Acrocanthosaurus.

真相： Becklespinax is a separate genus based on the tall-spined vertebrae. The name Altispinax was used for the same fossils, but Becklespinax is the current accepted name.2
