I am a bit annoyed that they didn't cite our paper on the Eocene carbon transfer by mass flows. I'm fairly sure at least one of the authors was aware of it.

🐴 For #FossilFriday the Eocene “dawn horse” Protorohippus venticolus (cast), housed at the Utah Field House of Natural History in Vernal, UT.
The original specimen—now in a private collection—is about 33cm (13 in) tall at the shoulder. It is one of two known specimens from the Fossil Butte Member at Fossil Butte National Monument, Wyoming.
I’ll be posting more about North American equids in the Midwest the next few months.

El Campanile giganteum es el caracol marino, o de cualquier otro tipo, más grande que se conoce. Vivió en el Eoceno (56-34 MdA) y midió hasta 120 cm de longitud, en el límite de tamaño de los gastrópodos, pues su pie deja de ser eficiente con mucho peso o superficie. 🏛️Centro de Biodiversidad Naturalis 📷Ghedoghedo #eoceno #eocene

Another great fossil sorting session this Sunday! It was an unusually fishy afternoon with lots of centra, scales, teeth, and fin rays from several different species being found, among the usual collection of teeth and bone fragments.
Our next session will be Sunday, Nov. 23 at MRU in Calgary. Everyone is welcome, so come on by!

The calcaneum (ankle bone) of a rodent from the Eocence Cypress Hills formation, Saskatchewan! This tiny bone is about 50 million years old and was found by one of our volunteers during a fossil sorting session.
If you'd like to get a chance to find your own fossil, our first session of the year is this Sunday!

El Arsinoitherium fue un mamífero del Eoceno tardío al Oligoceno temprano (36-27 MdA) con dos grandes y gruesos cuernos sobre la nariz y otro par pequeño sobre los ojos. Aunque tiene unas dimensiones similares al rinoceronte blanco, y recuerda a él, es un penungulado próximo a los elefantes, mientras los rinocerontes son perisodáctilos relacionados con los caballos y tapires. Además, sus cuernos son de hueso. #eoceno #eocene #oligoceno #oligocene

🐂 It’s a #Eocene #FossilFriday! 🐂 🐴🐘🦥🐪 This beautiful Megacerops skull is on display at the Trailside Museum in Crawford, Nebraska.
Megacerops upper molars feature a diagnostic W-shaped outer shearing surface, adapted for slicing through leaves and other plant material.
The Trailside Museum also houses the famous “Clash of the Mammoths” exhibit.

El Gyaclavator kohlsi fue una chinche de encaje (Tingidae) de finales del Eoceno temprano. Los machos, que son los que se han conservado, tienen un distiflagelómero (la porción distal de la antena) más grueso que podría haber usado para competir con otros machos o cortejar a las hembras. 📷Wrappler, 2015 #eoceno #eocene

El Poebrotherium era el antepasado de los camélidos, el primero con un aspecto que recuerda a las especies modernas, pero con el tamaño de una oveja. Entonces no estaba especializado ni en su hábitat, viviendo en llanuras, valles y bosques, ni en su alimentación, con una vida más similar a las gacelas. 📷Jonathan Chen #eoceno #eocene #mioceno #miocene

My 25 years of palaeoart chronology...
The 2022 Korean translation of Locked in Time (by Dr Dean Lomax & published by Columbia University Press) commissioned me to colourise my 50 greyscale illustrations. "Their Last Embrace" shows two Allaeochelys turtles copulating to their death in a toxic Eocene Messel Lake.
