Climate and Ecosystem Instability Delayed Dinosaur Success

LateTriassicDinosaursImage1.jpg

Climate and plant community instability may have hampered the success of dinosaurs in the tropics during the Late Triassic Period (235-201 million years ago), according to a study published in the Proceedings of the National Academy of Sciences (PNAS). This finding was reached by co-author Alan H. Turner, PhD, of Stony Brook University, and an international team of scientists by examining the sedimentary rocks and fossil record preserved in the Chinle Formation in northern New Mexico to investigate the environment in tropical latitudes during the Late Triassic.

Paleo-Engineering: New Study Reveals Complexity of Triceratops' Teeth

When it comes to the three-horned dinosaur called the Triceratops, science is showing the ancient creatures might have been a little more complex than we thought. In fact, their teeth were far more intricate than any reptile or mammal living today.

Study Suggests That Dinosaurs Were Warm-Blooded

DinosaurGrowthRate.jpg

Dinosaurs grew as fast as your average living mammal, according to a research paper published by Stony Brook University paleontologist Michael D’Emic, PhD. The paper, to published in Science on May 29, is a re-analysis of a widely publicized 2014 Science paper on dinosaur metabolism and growth that concluded dinosaurs were neither ectothermic nor endothermic—terms popularly simplified as ‘cold-blooded’ and ‘warm-blooded’—but instead occupied an intermediate category.

New research, led by the University of Southampton, has questioned the role played by ocean acidification, produced by the asteroid impact that killed the dinosaurs, in the extinction of ammonites and other planktonic calcifiers 66 million years ago.
