New insights into skeletal morphology of the oldest known ...
Umpiocha differs from Gleserocha in having a quadrate structure based on four struts and limbs that curve abapically beneath the apical structure. Discussion: Gleserocha is thought to be an evolutionary link between Variramus and Cornua, and as such includes a species transferred from each of the two https://www.sciencedirect.com/science/a ... 9814000312
The new genus is called Umpiocha, and the new species is called Umpiocha umpiensis.
