We tend to focus on the extinction of the dinosaurs, but the plant fossil record holds different parts of the story of life – and death – at the end of the Cretaceous The extinction event at the end of the Cretaceous Period, 66 million years ago, is the most well-known of the “Big Five”...
A new symmetrodont mammal (Trechnotheria: Zhangheotheriidae) from the Early Cretaceous of China and trechnotherian character evolutionAuthors:Bi et alAbstract:We report the discovery of Anebodon luoi, a new genus and species of zhangheotheriid symmetrodont mammal from the Lujiatun site of the Lower Cretaceous Yixian Formation, China.

Machairoceratops cronusi – “Bent Sword Horned Face” The discovery of skull bones that have proved to represent a new species of Late Cretaceous horned dinosaur has helped palaeontologists to plug a four-million-year gap in the Ceratopsidae fossil record. Show More Summary
When I was a kid (sometime in the Cretaceous period according my teenaged son), I remember hearing that my generation—Generation X—would never amount to much. Generation X grew up on a diet of John Hughes films, MTV, Beavis & Butt-head, hair metal, and arcade video games. Show More Summary

Small scale scrapes suggest avian display behavior by diminutive Cretaceous theropodsAuthors:Kim et alAbstract:A set of about 25 diminutive sub-parallel scrapes in the Cretaceous Haman Formation of South Korea fit the morphology of the small theropod track Minisauripus which is also known from this formation.

Reappraisal of the Early Cretaceous sauropod dinosaur Amargatitanis macni (Apesteguía, 2007), from northwestern Patagonia, ArgentinaAuthors:Gallina et alAbstract:Amargatitanis macni Apesteguía, 2007 was described as a purported titanosaur sauropod. Show More Summary
Oakland has three different bodies of conglomerate: from youngest to oldest they’re in the Orinda Formation (of Miocene age, maybe 10 million years old), the Oakland Conglomerate (Late Cretaceous, maybe 80 Ma) and the Knoxville Formation (Late Jurassic, about 165 Ma). Recently I’ve been getting fixated on the last one. I hope these photos from […]
Over a ton of 71 million-year old dinosaur fossils have been found in Antarctica. Most of them are from prehistoric marine reptiles and birds, even ducks that lived during the Cretaceous period. Researchers from the University of Queensland School of Biological Sciences and scientists from the United...
Fossils are cool and during an expedition earlier this year in Antarctica, scientists from the University of Queensland scientists collected a whole ton of them, some dating back to the Cretaceous era. Read more...
Mosasaurs – an extinct group of aquatic reptiles that thrived during the Late Cretaceous period – possibly were “endotherms,” or warm-blooded creatures. Mosasurs were large aquatic reptiles that went extinct at the end of the Cretaceous period, about 66 million years ago.
Fossilised Birds, Ammonites and Giant Marine Reptiles A team of international scientists including researchers from the University of Queensland and the Carnegie Museum of Natural History, have been showing off their vast collection of fossils after a very successful expedition to Antarctica earlier this year. The fossils, estimated to weigh over 1,000 lbs, provide evidence […]
Until now, the infant years of a baby titanosaur had been a mystery. Studies conducted on the bones of a young rapetosaurus, a titanosaurian sauropod, recently unearthed in the Upper Cretaceous Maevarans Formation in Madagascar, unlock some secrets. A research team comprised of scientists from Macalester College,...
Precocity in a tiny titanosaur from the Cretaceous of MadagascarAuthors:Rogers et alAbstract:Sauropod dinosaurs exhibit the largest ontogenetic size range among terrestrial vertebrates, but a dearth of very young individuals has hindered understanding of the beginning of their growth trajectory.

Researchers have completed a study on one of the few complete skulls of Sarmientosaurus muscacchioi, a titanosaurian sauropod dinosaur from the Upper Cretaceous period (about 95 million years ago). The study’s lead author, Ruben Martinez, director of the paleovertebrates lab at the National University of Patagonia San...
Sarmientosaurus musacchioi – A “Drop Head” Dinosaur The beautifully preserved skull of a new type of Titanosaur is helping scientists to understand the evolution of these herbivorous dinosaurs. Titanosaur skull fossils are exceptionally...Show More Summary
A Fish-Eating Enantiornithine Bird from the Early Cretaceous of China Provides Evidence of Modern Avian Digestive FeaturesAuthors:Wang et alAbstract:Modern birds differ from their theropod ancestors in lacking teeth and heavily constructed...Show More Summary
by “Cretaceous” Chris Wells Brazil is a beautiful country, but not in the same way as the Florida Keys, Hawaii, or Aspen. Everywhere in Brazil you have a wonderful dichotomy between the grotesque and the graceful. The entire country is … Continue reading ?
