TWO ULTRA RARE ASSOCIATED HYPACROSAURUS EMBRYO VERTEBRAE AND ASSOCIATED EGG SHELL FRAGMENT Two Medicine Formation - Browning, Montana, U.S.A. LATE CRETACEOUS PERIOD: 80 - 74 million years ago
Despite the tiny and seemingly dimension of these two dinosaur vertebrae and shell fragment, this is perhaps, one of the most rare of any dinosaur fossil you will find. All three fossils were found together in association in a Hypacrosaurus stebingeri nesting area of the famous Two Medicine Formation in Montana, U.S.A.. While eggshell fragments can occasionally be found on the public market, genuine DINOSAUR EMBRYO FOSSILS are so rare that seldom do they ever make it to the public for purchase. These specimens were collected on a private ranch with the owner's permission making them legal to own. It is quite probable that we will never offer or you will ever see this kind of rare material again ever for sale again.
As embryonic vertebrae, the processes have not formed yet. Both vertebrae are from different regions of the spine as can be seen in the varying thickness of the centrum which is all that has formed. Both vertebrae are COMPLETE with NO REPAIR and NO RESTORATION. Dinosaur embryo fossils have sold for well into the five and six figure prices. For a small fraction of the cost, you can own a genuine set of two embryo vertebra from this highly unusual dinosaur along with an original fragment of the creatures eggshell. For the dinosaur fossil enthusiast, it doesn't get more unique and rare as this! VERY HIGHLY RECOMMENDED!
Hypacrosaurus is a member of the Hadrosaurid family of dinosaurs. Its name means "high-ridged reptile" owing to the bony crest on the top of its skull. These dinosaurs had a large resonating nasal chamber that some scientist theorize would have been used for communication in the form of "bugling" like elk and moose. The nasal crests only fully formed in adults for different age Hypacrosaurs would have made different sounds. Similar to Maiasaura dinosaurs, Hypacrosaurus stebingeri is one of the most completely known dinosaurs because all life-stages of its bones have been found fossilized, from embryo to adult. Remains have been found in massive bonebeds suggesting that these creatures existed in herds. Communal behavior has also been attributed to large nesting grounds found where subadult skeletal remains have been found along with eggshell. Hadrosaurs were herbivores (plant-eaters) and only had teeth in the cheek area, not the front of the mouth. The many rows of teeth were perfect for effectively grinding up rough vegetation for easy digestion. This unique group of dinosaurs grew in sizes over 40 feet and probably weighed over 5 tons! In-depth studies of a variety of duckbill remains indicate that these were strictly land-based dinosaurs that walked predominantly on all fours but had the ability to stand on their hind legs. Hadrosaur remains have been found in China, North America, South America (Argentina) and Europe. EXTREMELY RARE MUSEUM-CLASS TYPE SPECIMEN - FIRST TIME OFFERED AND PROBABLY LAST! Vertebrae are .35" - .3" wide, eggshell fragment is .9" x .65" SOLD DB7-001 INCLUDES DISPLAY BOX Actual Item - One Only |
