#Yourpalaeolife The ECR survey is published @ecol-evol.bsky.social! Early career palaeontologists from all over the world have talked about their experience with fieldwork - how could you change your working practices to get more early career researchers into the field? doi.org/10.1002/ece3...

#Yourpalaeolife: Interrogating the Status of Fieldwork Among Early Career Palaeontology Researchers

This global survey of early career palaeontologists provides the first quantitative data regarding the prevalence of field skills training and field work among junior researchers of the discipline. T....

An assortment of ferns from the Late Cretaceous of North America, as described by Holian et al. 2026. Specimens come from the Denver, Hell Creek and lower Raton Formations. I only included those found in the Cretaceous (and excluded a couple I deemed not worth illustrating.)

One of my favourite papers - and most worrying. Favourite because it was a collaboration with the wonderful Margaret Collinson. And worrying because we showed the hot climates were not associated with peatland fires. Why should that be worrying? www.sciencedirect.com/science/arti...

Apollo 14 launched on Jan 31st, 1971 containing about 500 tree seeds (and also 3 human astronauts, for ballast, one presumes). These tree seeds were bold pioneers: Earthling visitors to our nearest neighbor in space. They returned to Earth & were planted across the country. MOON TREES!

Fifty years ago, the Apollo astronauts carried some souvenirs from Earth to the Moon, and then brought them back.

Another paper from our NASA-funded project on ferns has dropped! UWyoming MS student Fern (really!) Holian, developed a new schema for classifying fossil ferns, which are understudied. 🧪🌿☄️

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the.....

Finally, my first publication is out! We describe an exceptionally preserved new species of Metzgeriaceae liverwort from the Lower Cretaceous and reveal new insights into its growth mode and autoecology as an inhabitant of the subtropical wetlands of Las Hoyas. Give it a read if you are interested!

Up for another #fossil hunting tour near #Whitby. Who knows what wonders we'll find? Last time we found a piece of reptile (?) Bone with crinoids attached, and lovely plant fossils. If you want a tour then send me a DM. But be quick, August is filling up fast.

Following in the footsteps of pioneers like Nathorst, Antevs, and Schweitzer, we are setting out to explore the Late Devonian strata of Bear Island. Our goal: to uncover its unique endemic fossil flora and fauna from over 360 million years ago. 🌿🦴 #Paleobotany #Devonian #Svalbard #Bjørnøya
