Inside an 80-million-year-old egg: Dinosaur secrets uncovered with CT scans
Paleontologists have carried out CT scans of a dinosaur egg and the skull of a Giant Beaver to decode ancient secrets.
The New York State Museum’s paleontologists partnered with radiological experts at Albany Medical Center.
CT scans will allow experts to delve into the hidden internal structures of two exceptionally rare artifacts from the New York State Museum’s collection.
The scans were conducted on Wednesday, June 11.
“We were able to uncover new scientific insights into two of the Museum’s most intriguing specimens. The information gained from these scans will be an invaluable resource for our researchers and educators for years to come,” said Michael Mastroianni, Interim Deputy Commissioner of Cultural Education.
Duck-billed dinosaur egg
The dinosaur egg is believed to be from a Hadrosaur, also known as a duck-billed dinosaur, which lived during the late Cretaceous Period. It likely dates back to 70-80 million years.
While the egg’s exact origin is thought to be Asia, Hadrosaurs were known to have a wide distribution, including the Northeastern United States.
The CT scan of the dinosaur egg didn’t definitively show the density variations needed to confirm the presence of an embryo. The results were still highly encouraging. They suggest that the egg is intact, meaning its structural integrity remains largely preserved.
Furthermore, the scan revealed a small internal cavity, which scientists plan to examine more closely to identify its contents or significance.
This plant-eating dinosaur group flourished from about 85 to 66 million years ago in the Late Cretaceous Period, lasting until the extinction event that ended the era.
Ongoing paleontological research continues to reveal fascinating details about extinct creatures. A notable discovery occurred in January in Mongolia, where paleontologists unearthed a massive hadrosaurid dinosaur footprint measuring 92 centimeters (approximately 35 inches) across.
Rare skull
The team also performed scans on the skull of a Giant Beaver, or Castoroides ohioensis – an extinct Ice Age (Pleistocene epoch) mammal. It was an extinct rodent from the Ice Age, notable for its immense size – it was as large as a modern black bear.
This is the very first described skull of a Giant Beaver held in the Museum’s collection, making it a particularly important specimen.
Examining its skull could provide unprecedented details about its anatomy, potentially revealing insights into its diet, behavior, and evolution.
The Giant Beaver likely disappeared from Earth around 10,000 years ago. The extinction was thought to have been caused by a combination of shifting climate and habitat destruction.
“Wednesday’s scan has provided us with valuable insight to better our understanding of the reproduction and embryonic development of these extinct creatures. Our scientists are recognized as some of the best in their fields, but we can only see so much with the naked eye,” said Dr. Robert Feranec, Director of Research and Collections and Curator of Pleistocene Vertebrate Paleontology.
“There is much more we can learn from both the beaver skull and dinosaur egg, with these results acting as momentum pushing us closer to our answers. Collaborations like this are crucial to unlocking and preserving New York State’s past,” Feranec added.
Museum researchers will keep analyzing the scans in the coming weeks and months.
