The dinosaurs that forgot how to fly: 160 million-year-old fossils suggest they lost flight

160-million-year-old dinosaur fossils reveal surprising turn in flight evolution
An Upper Cretaceous confrontation between an adult Nanutyrnus (left) and two juvenile Tyrannosaurus rex (T. rex), as a semi-adolescent T. rex watches from a distance. The scene resembles a sort of “overture” to the famous T. rex trio on display in the Jane G. Pisano Dinosaur Hall at NHMLAC. Credit: Jorge Gonzalez

Scientists confirm: Nanotyrannus was a fully grown adult — not a T. rex cub

The study also sheds light on how large tyrannosaurs rapidly evolved into enormous apex predators at the top of the food web.

Study: Ancient pterosaurs took off with smaller brains than expected

  • No comments
New research using advanced fossil imaging shows that early pterosaurs – the first flying reptiles – may have mastered flight almost immediately upon their appearance, without needing a large brain like birds.

The dinosaur had a fleshy ridge over its neck and torso, a row of fleshy spines over its pelvis and tail, and hooves covering the tips of its hind feet. Credit: Dani Navarro

Paleontologists from the University of Chicago have unearthed fossils of a "duckbill" dinosaur in Wyoming that have been meticulously reconstructed in the university's fossil lab. These fossils preserve soft tissues and external features at impressive resolution, allowing scientists to reconstruct what it looked like

Among the notable findings: unique feathers known as tertiary feathers, which help close the gap between the wing members and the bird's body, thus enabling flight support - until now, these feathers have not been documented in dinosaurs related to birds.

Ukhaatherium nessovi, a giant Cretaceous-age animal discovered in 1994 in Mongolia's Gobi Desert by the Mongolian Academy of Sciences and the American Museum of Natural History, is one of the many mammals used to study the placental mammal tree of life. When the tiny creature's remarkably well-preserved skeleton was discovered This time, the researchers were surprised to find the presence of epipubic bones, which were attached to both sides of the groin. Today this feature is only found in egg-laying mammals such as the duck and marsupial mammals such as the kangaroo. But their presence in this fossil showed that the first placental mammals also shared the same feature.
