Fossil of a new #mammal species from the age of #dinosaurs discovered in #Mongolia's Gobi desert
phys.org/news/2025-04-fossil-m

New Late #Cretaceous zhelestid mammal from the Bayanshiree Formation, Mongolia app.pan.pl/article/item/app012

"The suggested age corresponds to the early spread of flowering plants in terrestrial ecosystems. The robust nature of the molars resembles those of seed- and fruit-eating #mammals"

Footprints of tail-clubbed armored #dinosaurs found for the first time phys.org/news/2025-04-footprin paper by Victoria Arbour et al.: tandfonline.com/doi/full/10.10

"The tracks date back to the middle of the #Cretaceous period, about 100 to 94 million years ago. No bones from #ankylosaurids have been found in North America from about 100 to 84 million years ago... These footprints show that tail-clubbed ankylosaurs were alive and well in North America during this gap in the skeletal fossil record."

My 25 years of palaeoart chronology...

The 2022 Korean translation of Locked in Time (by Dr Dean Lomax - Palaeontologist & published by Columbia University Press) commissioned me to colourise my 50 greyscale illustrations. "Our Refuge and Tomb" shows multiple species of fish living in and around enormous clams (Platyceramus platinus).

Deep-sea fish study reveals evolutionary marvels in Earth's hadal zone phys.org/news/2025-03-deep-sea

#Evolution and genetic adaptation of fishes to the deep sea sciencedirect.com/science/arti

"they confirmed a century-old hypothesis about deep-sea #fish evolution involving two distinct pathways. 'Ancient survivors' colonized the deep sea before the #Cretaceous mass #extinction, while 'new immigrants' account for the majority of modern #DeepSea species that emerged after the #MassExtinction."

Cretaceous #fossil from #Antarctica reveals earliest modern bird

#Cretaceous Antarctic bird skull elucidates early avian ecological diversity nature.com/articles/s41586-024

"Few #birds are as likely to start as many arguments among #paleontologists as #Vegavis. This new fossil is going to help resolve a lot of those arguments. Chief among them: where is Vegavis perched in the bird tree of life?"

#NewSpecies of Ornithomimidae #dinosaurs identified in Mexico phys.org/news/2025-02-genus-sp

A long-handed new ornithomimid dinosaur from the #Campanian (Upper #Cretaceous) Cerro del Pueblo Formation, Coahuila, #Mexico: Claudia Inés Serrano-Brañas et al. sciencedirect.com/science/arti

"it had long hands with a palm longer than its entire upper arm... their purpose was to allow the #dinosaur to reach into shrubs, trees or bushes to pull branches, twigs into its mouth"
