I have an #ichnology question. In Tralee Ireland I came across calcareous flagstones with amazing serpitiform trace fossils. I've never seen anything quite so large with such a form. Individual traces are perhaps up to 50cm long by 2-3cm wide. Has anyone a name for this? The closest I can think of is taenidium serpentium but that shows meniscate backfills, not evident here.

Answers greatfully received.

Another video from Paleo 2026 has been posted! Dr. Jon Noad explains different often-overlooked trace fossils and uses comparison with living traces to show how these fossils are more numerous than we think - we just need to know what to look for.

For those working on #tracks / #footprints / #ichnology, I've made a neat little addon for #blender that aligns a mesh to the horizontal at z=0 based on a few points. Open and up on github:

Happy #FossilFriday, check out some tiny tracks from the St. George Dinosaur Discovery Site! These darling little traces were likely made by very young coelophysid theropods, perhaps making their first romp around the ancient lake they called home. (1/2)

Happy #FossilFriday, check out some darling crocodylomorph tracks! 200 million years ago, small and snappy distant-croc-relatives, like Protosuchus, darted and splashed along a ripple-marked lakeshore and through silty riverbeds, leaving behind their traces. (1/2)

Happy #FossilFriday, check out these theropod tracks with scale scratch lines! As these animals either swam or waded through rivers, their tracks were pressed into the fine sediment at the bottom. These lines show the pattern of their scales cutting through the mud. (1/2)

I've got my days all sorts of mixed up and didn't even realize it was #FossilFriday! Here's a couple theropod tracks from Early Jurassic rocks in southern Utah as consolidation!

Join me for a bit of a longer #FossilFriday! Last week, I visited the Las Vegas Natural History Museum and had the pleasure of seeing this beautiful Dilophosaurus reconstruction by Brian Engh. Let's take a closer look! (1/5)

Happy #FossilFriday, check out these Brachycheirotherium tracks! These were made by aetosaurs--heavily armored, typically herbivorous animals that lived with other weird critters during the Late Triassic. As they waddled over floodplains, they left behind their traces. (1/2)
