Unusual features of the tracks, including relatively long, slender pedal digit impressions, do not match the pes of any known Cretaceous pterosaur, suggesting that the trackmakers are as yet unknown from the body fossil record. (bvsalud.org)

Because of the dominance of dinosaurs, mammals remained small and probably nocturnal. (historyoftheuniverse.com)
Unlike dinosaurs, who probably needed the Sun's heat to keep them warm, the mammals had fur to keep them warm. (historyoftheuniverse.com)
Mammals were also far more intelligent than dinosaurs. (historyoftheuniverse.com)
It is strange that while the mammals had better bodies and brains than the dinosaurs, even so for a long time they were unable to spread. (historyoftheuniverse.com)

Among the most complete dinosaur embryos ever found, the fossil suggests that these dinosaurs developed bird-like postures close to hatching. (unexplained-mysteries.com)
Scientists found the posture of Baby Yingliang unique among known dinosaur embryos-its head lies below the body, with the feet on either side and the back curled along the blunt end of the egg. (unexplained-mysteries.com)
Previously unrecognized in dinosaurs, this posture is similar to that of modern bird embryos. (unexplained-mysteries.com)

The extinction of non-avian dinosaurs 65 million years ago is a perpetual topic of fascination, and lasting debate has focused on whether dinosaur biodiversity was in decline before end-Cretaceous volcanism and bolide impact. (nature.com)
At least some dinosaur groups, however, did endure long-term declines in morphological variability before their extinction. (nature.com)
