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 ?

Did Seed Eating Save the Birds at the Cretaceous Paleogene Extinction?

When the dinosaurs became extinct, plenty of small bird-like dinosaurs disappeared along with giants like Tyrannosaurus and Triceratops. Why only some of them survived to become modern-day birds remains a mystery. Now, researchers reporting...Show More Summary

Why did Several Dinosaur Families go Locally Extinct ONLY in Europe During the Cretaceous?

Researchers have used 'network theory' for the first time to visually depict the movement of dinosaurs around the world during the Mesozoic Era - including a curious exodus from Europe.The research, published today in the Journal ofShow More Summary

It Was Seeds That Saved Some Dinosaurs From Extinction

Everyone with an outdoor bird feeder or a pet parrot knows that birds love seeds. Apparently, this love goes all the way back to the Cretaceous Period as new evidence suggests it was their seed diet that saved the raptor ancestors of modern birds from extinction after...

Glacial dropstones in the western Tethys during the late Aptian–early Albian cold snap

Glacial dropstones in the western Tethys during the late Aptian–early Albian cold snap: Palaeoclimate and palaeogeographic implications for the mid-CretaceousAuthors:Rodríguez-López et alAbstract:The late Jurassic–early Cretaceous is commonly considered the only cold climatic interval in Earth history without any direct evidence of polar ice. Show More Summary

Seed Eating May Have Helped Birds Survive

Seed Clue to How Birds Survived the Cretaceous Extinction Event The birds that are around today, might have the seed-eating habit of an ancestor to thank for enabling their kind to survive the extinction event that saw the demise of the dinosaurs.  A study published in the scientific journal “Current Biology” suggests that whilst the […]

The Ability to Enter Torpor Might Have Saved Mammals Across the KT/K-Pg Mass Extinction

Cool echidnas survive the fireAuthors:Nowack et alAbstract:Fires have occurred throughout history, including those associated with the meteoroid impact at the Cretaceous–Palaeogene (K–Pg) boundary that eliminated many vertebrate species. Show More Summary

Symbiosis Between Lobsters and Bivalves During the Aptian Cretaceous

Bivalves on mecochirid lobsters from the Aptian of the Isle of Wight: Snapshot on an Early Cretaceous palaeosymbiosisAuthors:Robin et alAbstract:Fossil symbioses (Bary 1879) that are not recognized in modern assemblages are rare. This holds true especially because fossil remains of interspecific association are sporadic and difficult to document. Show More Summary

A new Cenrosaurine Ceratopsian From Campanian Cretaceous Mexico

A Centrosaurine (Dinosauria: Ceratopsia) from the Aguja Formation (Late Campanian) of Northern Coahuila, MexicoAuthors:Rivera-Silva et alAbstract:While centrosaurines and ceratopsids in general are abundant in the Late Campanian of northern Laramidia, they are much less commonly found in southern Laramidia. Show More Summary

Apatoraptor pennatus: a new Caenagnathid Oviraptorosaur From Cretaceous Canada

A new caenagnathid (Dinosauria: Oviraptorosauria) from the Horseshoe Canyon Formation of Alberta, Canada, and a reevaluation of the relationships of CaenagnathidaeAuthors:Funston et alAbstract:Our understanding of caenagnathids has benefited from recent discoveries, including nearly complete skeletons from the Hell Creek Formation of Montana. Show More Summary

New Findings in the Study of Feathered Dinosaurs and Pterosaurs

New Findings in the Study of Feathered Dinosaurs and PterosaursAuthors:???Abstract:An oviraptorid dinosaur Huanansaurus ganzhouensis, belonging to the derived oviraptorid dinosaur, was discovered from the Late Cretaceous deposits in Ganzhou, Jiangxi Province. Show More Summary

New Remains of Late Cretaceous Giant Bird Gargantuavis philoinos Found in France

New remains of the giant bird Gargantuavis philoinos from the Late Cretaceous of Provence (south-eastern France)Authors:Buffetaut et alAbstract:Two incomplete pelves of the giant bird Gargantuavis philoinos are described from Late Cretaceous deposits at Fox-Amphoux (Var, south-eastern France).

“Egg-citing” Dinosaur Egg Discovery from China

Dinosaur Eggs from the Early Cretaceous Parts of China have provided palaeontologists with ample evidence of dinosaur nesting behaviour, fossils of nests, eggshells and complete eggs themselves have been excavated from a number of locations.  Guandong Province (southern China) in particular is famous for the relative abundance of dinosaur egg fossils that have been found. […]

Were Mosasaurs Warm Blooded?

Endothermic mosasaurs? Possible thermoregulation of Late Cretaceous mosasaurs (Reptilia, Squamata) indicated by stable oxygen isotopes in fossil bioapatite in comparison with coeval marine fish and pelagic seabirdsAuthors:Lynn Harrell...Show More Summary

Carbon cycle history across the Jurassic–Cretaceous boundary

Carbon cycle history through the Jurassic–Cretaceous boundary: A new global ?13C stackAuthors:Price et alAbstract:We present new carbon and oxygen isotope curves from sections in the Bakony Mts. (Hungary), constrained by biostratigraphy...Show More Summary

Marine Biota was Brought into Songliao Lake by Marine Incursions During the Late Cretaceous

Late Cretaceous marine fossils and seawater incursion events in the Songliao Basin, NE ChinaAuthors:Xi et alAbstract:The Songliao Basin is the largest non-marine oil-bearing basin in China. Because of the absence of substantial evidence, the hypothesis of seawater incursion events into the Songliao Basin remains controversial. Show More Summary

Origins of Malaria Traced Back 100 Million Years

Malaria Dates Back to the Cretaceous The disease malaria which is a mosquito-borne infectious disease of humans and other animals caused by parasitic protozoans belonging to the Plasmodium type, killed an estimated 438,000 people in 2015.  The World Health Organisation (WHO) reports that there were some 214 million cases last year and currently, this debilitating and […]

Evidence for an Aptian Cretaceous Carbon Perturbation in China

Lacustrine sedimentary record of early Aptian carbon cycle perturbation in western Liaoning, ChinaAuthors:Zhang et alAbstract:The early Aptian abrupt carbon isotope excursion in marine carbonate and sedimentary organic matter reflects a major perturbation in the global carbon cycle.

Potentially NO Aptian and Albian Cretaceous Atmospheric CO2 changes during oceanic anoxic events

Aptian and Albian atmospheric CO2 changes during oceanic anoxic events: Evidence from fossil Ginkgo cuticles in Jilin Province, Northeast ChinaAuthors:Sun et alAbstract:The Early Cretaceous was a time with super-greenhouse conditions and episodic global oceanic anoxic events. Show More Summary

Montirictus kuwajimaensis: a new Tritylodontid Mammaliamorph From Barremian/Aptian Cretaceous Japan

A new Early Cretaceous tritylodontid (Synapsida, Cynodontia, Mammaliamorpha) from the Kuwajima Formation (Tetori Group) of central JapanAuthors:Matsuoka et alAbstract:We describe tritylodontid remains from the Lower Cretaceous Kuwajima Formation (Tetori Group) in central Japan as representing a new genus, Montirictus kuwajimaensis, gen.
