Agaricocrinus is a common Mississippian crinoid, but very beautiful. This specimen is from the Edwardsville Fm of Indiana near Crawfordsville. Each arm has delicate pinnules that would filter water for food.

Happy #FossilFriday from the Gobi Desert, Mongolia 🏜️🦴

The skeleton likely belonged to Sloanbaatar, a multituberculate #mammal from the L. Cretaceous Baruungoyot Fm, highlighting a glimpse into the diversity of Mesozoic mammals that lived alongside dinosaurs. πŸ¦•πŸ€πŸ

Not the easiest #FossilFriday as war rears its head again here in the Middle east...
A throwback from quieter times: The oldest known sea turtle, Desmatochelys padillai from Colombia. Despite their ancient appearance, turtles returned to the seas at a much later date than many other reptile groups

A portrait page with a full restored branch onto the left. It has 6 palm like leaves at the end of one branch, hiding a cone, with a second mature cone below it. On the top right is a male floral organ, which is start shaped, and in the bottom right is a cut-way of the female cone showing its development.

I have another #paleobotany restoration guide for this #FossilFriday. This time, it's Kimuriella densifolia, a whole plant bennettitalean from the Late #Jurassic of Japan.
This plant is composed of three organ taxa: Williamsonia, Zamites, and Weltrichia.

πŸŽ‰ Great news: the UK’s emissions fell to their lowest level in 150 years last year, with coal use roughly halving.

π–£˜ We also saw record-breaking generation from renewable sources, especially wind & solar.

happy #fossilfriday! this is elginia, a pareiasaur from late permian scotland and china. it was a small herbivore – about 60cm long – distinguished by the elaborate spines that ornamented its skull, presumably used for display

Fossil Friday #307: Euphoberia sp. From PitΒ 11 For today, we have a very nice Mazon Creek millipede. Euphoberia is an extinct genus of millipede found in both Europe and North America. The genus was erected by Β Fielding Bradford MeekΒ and Amos Henry Worthen when they described Euphoberia armigera as a centipede in 1868.

The Butterbur are flowering along the canal now. Like the early Celandine and Primrose flowers they are a great source of nectar for bees when flowers are still scarce early in Spring. They flower before the huge leaves appear with their felt like upper surface.

During the Silurian period, over 400 million years ago, the West Midlands was covered by a shallow, tropical sea. Fossil evidence for this includes this Marsupiocrinus genus of extinct crinoid (sometimes called a sea lily), found in the Much Wenlock Formation in Dudley.

It’s the Cambrian trilobite genus Olenellus from the Kinzer formation of Lancaster County, PA. There’s a surprising amount of Cambrian goodies from that formation but it’s hard to find outcrops. #fossilfriday
