Paleontologists from the University of Zaragoza, in Spain, have found a new species of crocodile that lived with the last dinosaurs of the past and laid the fattest eggs ever, according to a report in News week.
The eggshells of these crocodiles were found in the Ribagorza region of the province of Huesca in northeastern Spain by paleontologists working at NOVA University Lisbon and the Catalan Institute of Human Paleoecology and Social Evolution, the outlet said.
The study was published July 21 in the peer-reviewed academic journal Historical Biologyand the university released a statement on the discovery on Wednesday.
Historical Biology is an international peer-reviewed publication that publishes original research and review articles on advances in the sciences related to the biology of extinct species and the history of life in geological time.
In the study, the researchers detailed the detailed process of locating more than 300 eggshell fragments found near Biascas de Obarra in the Beranuy municipality of Huesca.
University of Zaragoza told Zenger News in a statement: “The fragments found correspond to the thickest crocodile shells found worldwide in the fossil record. Their discovery increases the paleontological richness of the Ribagorza region and reaffirms its importance worldwide in ending the Cretaceous extinction to study.”
According to the experts, the eggshells have their origin in the Upper Cretaceous period, and the “fragments were part of the eggs laid by crocodiles that lived with the last Iberian dinosaurs at the end of the Cretaceous,” News week further said.
