👉 Gonypetinae are a group of extinct reptiles that lived during the Late Cretaceous period, about 68 to 59 million years ago. They were characterized by their large, flat head and body shape, with a long neck for feeding on insects and small animals. Gonypetinae are known from only one species, the "Gonpypetus" or "Gonpypetum", which lived during this time period.
