Genus: Mixopterus

...a genus of Mixopteroid eurypterids (sea scorpions) that lived during the late Silurian period. Mixopterus was characterized by its robust exoskeleton and claws which held short spines, which likely helped it hold onto 'slippery' prey. Like the unrelated Megalograptus Mixopterus's telson was curved into a spine which gave it a superficial appearance to a scorpion.

Eurypterida

Eurypterida, or more commonly, sea scorpions, are ancient relatives of chelicerates (spiders and scorpions) that thrived from the Ordovician to the Permian Periods 460 to 248 mya, predating the earliest fishes. They are named for the wide, wing-shaped lobes on either side of the body, which were used to propel this predator through the waters as it hunted. Eurypterids were incredibly successful, with a near global distribution.

The long spine at the end of the tail of most Eurypterids may have been used to inject venom, but there is no evidence that any members of Eurypterida were venomous. The animals also possessed one pair of compound eyes, and another set of smaller eyes called ocelli between them. The stout walking legs of some species suggest that they may have been amphibious, and may even have been the first animals to colonize land.

The largest known Eurypterid attained a length of 2.5 m (8 ft 2 in), making it the largest arthropod ever discovered. They went extinct in the Permian-Triassic extinction event 251 mya.
