Desiccation polygons in thin microbial mats. As mats dehydrate and contract, the edges of polygons roll inwards to produce characteristic open dishes. These edges are particularly susceptible to erosion and transport - acting to ‘seed’ new mats if deposited in a suitable environment. #SabkhaSaturday

Outcrop of metasandstone in the 1.7 billion year old Yavapai Schist in central Arizona USA that has some intriguing relict sedimentary structures, including trough and hummocky cross-stratification and cobble-sized rip-up clasts. The huge hummocky crossbeds, with rip-ups, could be a tsunamite. 🧪⚒️

Dinosaur National Monument contains over 1500 fossils from 11 different species of dinosaurs- and something of a mystery. Despite the immense number of bones preserved here, only a single specimen shows signs of having been gnawed by a predator. #paleontology #dinosaurs #scicomm #paleosky

It's Fossil Friday! This is the holotype skull of Diabloceratops, discovered in the Wahweap Formation. While its horns may have been for identifying other members of its species, they could have served as protection against its contemporary tyrannosaurid, Lythronax. 🧪

A chondrite meteorite. The little circles are chondrules, rock vapor condensate grains - like space ooids; the oldest objects in our solar system. Chondrites are cosmic dust bunnies, as the chondrules glommed onto each other via static cling. #spaceooids ⚒️

Some fossils make you go WHOA at first sight and this is one of them: an ancient grasshopper nest with 50 intact eggs. It's the first fossil grasshopper nest ever found! Discovered at John Day Fossil Beds National Monument in Oregon, it offers a peek at insect reproduction 29 million years ago 🧪

A bony mosaic. These are osteoderms that covered the back of the ankylosaur Sauropelta. Even though such bones are often referred to as “body armor,” they were probably important for display, regulating body temperature, and calcium storage, too. 🧪
