D.N.FossilmanLithuania Posted May 3, 2018 Share Posted May 3, 2018 Yes, looks like scute, not bone. It should not be armadillo if there are no any Cenozoic rocks in your area, so probably turtle shell element. Best Regards Domas Link to comment Share on other sites More sharing options...

Scutes in turtles are made of keratin and cover the bone like scales . Link to comment Share on other sites More sharing options...

No evidence for cranial material of somewhat dinosaur. It's turtle, imo some part of hyo- or hypoplastron (see Fig 3 in attached Link/Article for example) - your fossil shows the typical "rib melted with the plastron". https://www.researchgate.net/publication/271742886_A_new_turtle_from_the_Xiagou_Formation_Early_Cretaceous_of_Changma_Basin_Gansu_Province_P_R_China 3 Link to comment Share on other sites More sharing options...
