👉 The term "Stephanoberycidae" refers to a group of extinct or extinct-like species that lived during the Late Cretaceous period, which was about 65-70 million years ago. These species are characterized by their large head size, flattened bodies, and small eyes with large pupils. The steppe grasses they grew on were particularly suitable for grazing because of their long stalks and thick leaves that provided shelter from the harsh desert conditions.
