This is tremendous, but let’s all revise our expectations about “gigantic”:
These ancient sea monsters grew to about 70 centimeters (2.7 feet) long and “looked like something completely out of this planet,” with massive frontal appendages for grasping prey, huge eyes on stalks, and a mouth shaped like a piece of canned pineapple, Vinther told Live Science.
In term of size, this is not giant squid territory. Does anyone know why Cambrian creatures were comparatively small?
