Polished "Gem" Hadrosaurid Dinosaur Vertebra Pair Kritosaurus sp. Late...

Polished "Gem" Hadrosaurid Dinosaur Vertebra Pair Kritosaurus sp. Late Cretaceous Aguja Formation Brewster County, Texas, USA A pretty amazing Dinosaur vertebra in its own right, this fossilized bone evidenced great shape, nice form, and pleasing reddish-brown, mottled coloration. Of course, this has been cut into essentially a matched pair, with each half displaying a spectacular, polished window face showcasing a nicely preserved trabecular structure of the "gem" bone. Found on private ranch lands in West Texas, the fossil pairing dating to the Late Cretaceous represents the Kritosaurus variety, of which only seven have been found in the Aguja Formation. Discovered with a backhoe operation, the preservation is the result of close proximity to an extinct hydrothermal vent. This is quite unusual for a Texas find. The reflectively finished faces display a pleasing brownish coloration and intricate patterning over the fairly sizable primary surfaces. The exterior features of each specimen are equally impressive. Larger Half Measurements: 5.29 x 4.11 x 1.94 inches (13.44 x 10.44 x 4.94 cm) HID09710052018 © 2024 Heritage Auctions | All Rights Reserved
