Why is "Hibbertopteridae" trending?

Wikipedia Overview

Hibbertopteridae is a family of eurypterids, an extinct group of aquatic arthropods. They were members of the superfamily Mycteropoidea. Hibbertopterids were large, broad and heavy animals unlike virtually every other group of eurypterids, which are commonly streamlined and lightweight. Their bizarre morphology is so unusual that they in the past have been thought to represent an entirely distinct order of chelicerates. Fossils of the family first appear in deposits of the Middle Devonian, and the last known fossils representing hibbertopterids are known from deposits of the Permian period. The hibbertopterids represent the last known living eurypterids, with the latest known definitive species, Campylocephalus permianus, being argued to have went extinct during the late Early Permian-early Middle Permian or the Late Permian; the other possible Late Permian taxon, Woodwardopterus freemanorum, may instead represent a true scorpion.
