Dinosaur Eggs Have Never Been Discovered This Far South Before
Researchers are hypothesizing how a clutch was kept warm The post Dinosaur Eggs Have Never Been Discovered This Far South Before appeared first on Nautilus .
A team of researchers have discovered dinosaur eggshell fragments in Argentina, further south than any other known titanosaur nesting site. Titanosaurs, massive long-necked herbivores, were once believed to have nested primarily around the equator, but the new find suggests they also nested in cooler climates with less sunlight.
The eggshell porosity indicates they likely nested in large mounds of vegetation to retain warmth from decaying plant matter, solar radiation, or geothermal activity. Titanosaurs, some of the largest creatures to ever walk the Earth, probably did not sit atop their eggs to keep them warm, unlike modern crocodiles and birds. The study, published in Royal Society Open Science, anticipates that future discoveries of egg fossils at higher latitudes in Argentina, Canada, and beyond will deepen our understanding of dinosaur nesting strategies in colder environments.
