The Forgotten Creatures Who Ruled Before the “Great Death”

Researchers have uncovered in "Southern Pangaea" (now the southern part of Africa) fossils of creatures that lived shortly before the event known as the "Great Dying," which wiped out about 70% of terrestrial species and an even larger proportion of species

Ukhaatherium nessovi, a giant Cretaceous-age animal discovered in 1994 in Mongolia's Gobi Desert by the Mongolian Academy of Sciences and the American Museum of Natural History, is one of the many mammals used to study the placental mammal tree of life. When the tiny creature's remarkably well-preserved skeleton was discovered This time, the researchers were surprised to find the presence of epipubic bones, which were attached to both sides of the groin. Today this feature is only found in egg-laying mammals such as the duck and marsupial mammals such as the kangaroo. But their presence in this fossil showed that the first placental mammals also shared the same feature.
