For #FossilFriday, walking with dinosaurs ~100 million years too late at the Davenport Ranch dinosaur tracksite (1st documented in 1940), near Bandera TX on a @geosociety.bsky.social pre-meeting field trip just 2 weeks ago. Tracks show evidence of herding sauropods & big theropods. 🧪🪨⚒️🦖🦕🐾 #ichnology

Here's the research article reporting on the newly reinterpreted Mayan Dude Ranch sauropod trackway, which was published earlier in 2025. Kudos to "Jurassic Judy" for her discovery & for her well-deserved inclusion as a coauthor on the study. www.tandfonline.com/doi/full/10.... 🧪🦕🐾🪨 #ichnology

More news about an incredible a Middle Jurassic (~170 mya) dinosaur tracksite near Oxford (U.K.), which includes one of the longest continuous dinosaur trackways in the world, made by a big sauropod. 🧪🦕🐾🪨 #ichnology
Back in June we were back on the Oxfordshire “dinosaur highway”, excavating more dinosaur tracks with our teams from the Universities of Birmingham, Oxford & Liverpool John Moores. The BBC have a story out today about our work at the site:

One of the longest sets of dinosaur footprints in the world has been discovered in a limestone quary near Bicester, in Oxfordshire, England.

A fringe benefits of following people on Bluesky who are not in my academic disciplines (ichnology, paleontology, taphonomy) is learning about unique modern animal-behavioral modes & traces: e.g., pigs using lumps of biscuit dough to construct dens for attracting avians & ambush predation. 🧪🐖🕳️🐦
I read about a pig farm that would get uncooked biscuit dough rejects from a Pillsbury factory, big lumps of dough. The pigs would chew dens in the dough, climb inside, and then wait for starlings.

For #FossilFriday, an ichnological 2-for-1 special in a body fossil: a termite nest packed with termite coprolites (feces) in an araucarian tree trunk, from the Early Cretaceous (~125 mya) of Victoria, Australia; oldest termite nest in Australia & largest wood nest from this time. 🧪🪵🪨⚒️ #ichnology

I love seeing these examples of how the effects of ancient behaviors influence modern behaviors, especially when trace fossils from vastly different environments nudge them this way or that. 🧪🐾🦖 #ichnology #FossilFriday

Howdy! I'm a [looks at Bluesky handle] ichnologist, with ichnology = the study of traces: tracks, burrows, borings, nests, toothmarks, feces, & other indirect signs of behavior. I've worked on modern & fossil traces made by lots of different critters, & I love talking/teaching about them. 🧪🐾

Existing knowledge of the tracks left by sauropod dinosaurs (loosely ‘brontosaurs’) is essentially two-dimensional, derived mainly from footprints exposed on bedding planes, but examples in the Broome...

Today, in my first-year-student seminar (the "tracking class"), we'll be outside, looking for tracks & trails in Lullwater Preserve of Emory U. (Atlanta GA). Here are photos of students taking their "final exam" there in December 2016 (R) & opossum tracks + clam burrows (L). #ichnology

Although I had not heard of the "Clearwater Monster" before now, I very much approve of its theropod-like tracks in this fun/terrifying illustration by @danielloxton.bsky.social. #ichnology
New illustration, created as a companion piece for my recent interview on the Squaring the Strange podcast, depicting the mythical "Clearwater monster" (which I previously investigated for my final Skeptic mag story).

For #TheropodThursday (why not?), a large (40-cm long) theropod #dinosaur track from the Cretaceous (~100 mya) Glen Rose Formation, Glen Rose TX. This dinosaur stepped on former lagoon sediments that had U-shaped invertebrate burrows, which were likely unoccupied when dino-stomped. #ichnology 1/2
