How Giant Dinosaurs Used a Crocodile Trick to Raise Their Young in Freezing Climates
https://www.bioscience.com.pk/en/subject/biology/this-75-ton-dinosaur-nested-in-a-freezing-climate-like-todays-new-york-using-a-trick-crocodiles-still-use-todayrevealed an unusually high degree of porosity. In an exposed environment, such thin and porous shells would have caused the embryos to desiccate rapidly. The researchers conclude that titanosaurs likely bypassed this threat by employing a nesting...
