A new species of lizard from the Late Cretaceous era links New World lizards with those from the Old World for the first time.
A stem acrodontan lizard in the Cretaceous of Brazil revises early lizard evolution in Gondwana. 2015. Nature Communications University of Alberta paleontologists have discovered a new species of lizard, named Gueragama sulamericana,...Show More Summary
Paleontologists have discovered a new species of lizard, named Gueragama sulamericana, in the municipality of Cruzeiro do Oeste in Southern Brazil in the rock outcrops of a Late Cretaceous desert, dated approximately 80 million years ago.
We examined the stratigraphic distribution of ammonites at a total of 29 sites around the world in the last 0.5 myr of the Maastrichtian. We demarcated this interval using biostratigraphy, magnetostratigraphy, cyclostratigraphy, and data on fossil occurrences in relation to the K/Pg boundary in sections without any facies change between the highest ammonites and the […]
A freshwater plant from the Cretaceous era has been identified as one of the first ever flowering plants.
Indiana University paleobotanist David Dilcher and colleagues in Europe have identified a 125 million- to 130 million-year-old freshwater plant as one of earliest flowering plants on Earth.The finding, reported Aug. 17 in the Proceedings...Show More Summary
by “Cretaceous” Chris Wells The Houston Museum of Natural Science started small. Back in 1909, when the museum was founded, you could probably see everything we had to offer in 30 minutes. But since our opening, HMNS has been growing exponentially. … Continue reading ?
Biologist Provides Fresh Insight into Early Cretaceous Dinosaur Tracks Many of us, will this summer, go for a stroll along the beach whilst on a visit to the seaside. It seems this pastime may have been popular with Theropod dinosaurs too. Biologist Pernille Venø Troelsen of the University of Southern Denmark, has provided a fresh perspective […]
Theropod Diversity Study (Upper Cretaceous South Pyrenees Basin of Spain) Large dinosaur bones might make the headlines and attract the most media attention, but an analysis of shed Theropod teeth, some of them tiny, indicate that there were potentially many more different types of Theropod dinosaur roaming around Spain in the Late Cretaceous. Dinosaurs were […]
Quantitative temperature records of mid Cretaceous hothouse: Evidence from halite fluid inclusionsAuthors:Zhang et alAbstract:Quantitative temperature reconstructions for the mid Cretaceous are still rare although its typical greenhouse climate is regarded as one of the best analogues for future global warming.

Researchers have examined one of the smallest parts of the fossil record -- theropod teeth -- to shed light on the evolution of dinosaurs at the end of the Cretaceous. Findings have effectively quadrupled the dinosaur diversity in the area of study, including the exceptional site of Laño. There were previously only two known species in the area.
A new study using the fossil record of turtles over the last 220 million years shows that warm climates had an impact on their range and diversity
A four-legged snake from the Early Cretaceous of GondwanaAuthors:Martill et alAbstract:Snakes are a remarkably diverse and successful group today, but their evolutionary origins are obscure. The discovery of snakes with two legs hasShow More Summary
Red Iron-Pigmented Tooth Enamel in a Multituberculate Mammal from the Late Cretaceous Transylvanian “Ha?eg Island”Authors:Smith et alAbstract:Mammals that inhabit islands are characterized by peculiar morphologies in comparison to their mainland relatives. Show More Summary
The several million years preceding the Cretaceous/Paleogene (K/Pg) boundary has been the focus of many studies. Changes in ocean circulation and sea level, extinctions, and major volcanic events have all been documented for this interval. Important research questions these changes raise include the climate dynamics during the warm, but not hot, time after the decay […]
A Multi-disciplinary Perspective on Habitat Preferences among Dinosaurs in a Cretaceous Arctic Greenhouse World, North Slope, Alaska (Prince Creek Formation: Upper Maastrichtian)Authors:Fiorillo et alAbstract:The Prince Creek Formation...Show More Summary
Zhenyuanlong – A Big Bird, well, Almost This week we have seen the latest feathered and fluffy dinosaur revealed from the Lower Cretaceous deposits of Liaoning Province, north-eastern China. Scientists from the University of Edinburgh including the very talented Dr. Steve Brusatte, in collaboration with colleagues from the Institute of Geology (Chinese Academy of Geological […]
First record of Polycotylidae (Sauropterygia, plesiosauria) from the Upper Cretaceous of AntarcticaAuthors:Novas et alAbstract:In the present paper we report the incomplete skeleton of an indeterminate polycotylid that includes the articulated pelvic girdle. Show More Summary
Researchers have discovered fragments of fossilized dinosaur eggs in Southern Japan, according to a June 29 report in the journal Cretaceous Research. The 90 eggshell fragments once housed five different types of dinosaurs, all of them small. Show More Summary
