70-Million-Year-Old Dinosaur Egg Discovered in Argentina Appears Remarkably Preserved
RIO NEGRO, ARGENTINA – A team of paleontologists in Argentina has unearthed a remarkably well-preserved dinosaur egg, estimated to be over 70 million years old. The discovery, made in the Patagonian region, is believed to be the first of its kind found in South America.
The egg, approximately the size of an ostrich embryo, was found alongside evidence of a nest, according to posts on the Laboratory of Comparative Anatomy and Vertebrate Evolution’s (LACEV) Instagram page. team leader Federico Agnolín,a world-class anatomist,is shown handling the egg,which appears almost hard-boiled in its immaculate condition.
“this is quite possibly the FIRST finding of this guy in South America,” reads a caption accompanying one of the instagram posts. “As you can see, this fossil is over 70,000,000 years old, and HE WASN’T ALONE, WE FOUND A NEST.”
researchers believe the egg likely belonged to the Bonapartenykus genus – a small, carnivorous theropod dinosaur that lived during the late cretaceous period.
“It’s unusual to find the egg of a possible carnivorous dinosaur, much less in this state,” said researcher José Luis Muñoz. He noted the difference between these eggs and those of sauropods, stating, “sauropod dinosaur eggs…had spherical eggs, like enormous balls, with thicker shells.”
The fragility of carnivorous dinosaur eggs is attributed to their evolutionary link to birds. “Their eggs are more avian-like, since the carnivorous dinosaur lineage is the one that will give rise to birds,” Muñoz explained.”Thus, they’re going to be more delicate eggs, with much thinner shells, more prone to destruction.”
The egg and other discoveries from the site will be sent to the Argentine museum of Natural Sciences for further examination. Scientists will conduct scans to determine if the fossilized shell contains an embryo, which could reveal the specific species of dinosaur and provide insights into dinosaur evolution.
“If it’s a carnivorous dinosaur, it would teach us, for example, how dinosaur eggs evolved into birds,” Muñoz said. “It could show us what their chicks were like,what state they were in at birth,weather they’re fully developed or not… Any details it provides will be novel and incredibly captivating.”
Researchers have been contacted for comment regarding the possibility of DNA extraction.
