For #FossilFriday, we're taking a look at not true fossils, but preserved mud cracks. Below this incredible natural cast of a Eubrontes track, the wide mudcracks were formed during a period of drought and later preserved by water carrying sediment. (1/3) #paleontology#ichnology
Happy #FossilFriday, here's a natural cast of a hadrosaur track from the Blackhawk Formation in Utah! Groups of hadrosaurs walked across a squishy swamp during the Early Cretaceous, leaving behind prints that would have later been filled in by sand. (1/2) #paleontology#ichnology#dinosaur#science
Check out these swim tracks attributed to a prosauropod for #FossilFriday! Four-toed Sarahsaurus would have lived nearby during the Early Jurassic, and it could have swam through shallow rivers connected to an ever-shrinking lake, Lake Whitmore. (1/2) #paleontology#ichnology#dinosaur#science
Happy #FossilFriday! Here's a partial Eubrontes track with skin impressions, found and housed at the SGDS, compared to a cast of an owl foot. Note how the paw pads are in similar places and how much the scales look alike! Birds ARE living dinosaurs. #paleontology#ichnology#dinosaur
Happy #FossilFriday! While not true fossils, ripple marks can help indicate where fossils may be found. As they are often formed by moving water, ripple marks and other sedimentary structures give evidence of where water used to be. #paleontology#ichnology
It's another #FossilFriday, and I've got a fun one for you. This 200-million-year old coprolite, possibly produced by a dinosaur, is absolutely packed with fish scales! Note how they have been tightly rolled around a red central mass in the coprolite. #paleontology#ichnology
