20926 - Top Quality "Flying" 2.16 Inch Harpes perradiatus Lower Devonian Trilobite Carcharodontosaurus Institutions and collections UCLA:Impressive specimen, prepared in an exceptional way. This trilobite has been prepared as free standing. This type of preparation requires meticulous work of tens of hours. Of course, some sectors during the preparation process have been fractured and glued again, with slight restorations in the fracture zones. A preparation like this without small restorations is impossible. It is an authentic specimen of Museum Grade.
