An ichnofossil: Ordovician trilobite trackways, preserved as locomotion traces on the ancient sea floor.
Unlike body fossils, these are trace fossils recording behavior rather than anatomy.

An elongated burrow preserved as a relief on coarse-grained sediments. A scale bar shows that the observable part is around 20 cm long and 1-1.5 cm wide. It appears that the burrow branches on the right of the image.

#FossilFriday: an ichnofossil - probably a crustacean burrow - from the Pliocene (the site is dated at 3.7-3.5 Ma) of the Cervo River "Canyon", Biella Province, Piedmont.

For #FossilFriday, a favourite #ichnofossil: the tracks of a (probably) Iguanadon at Portugal's Natural Monument of Lagosteiros. It's on the tip of Cabo Espichel, which is rife with dinosaur tracks.

#FossilFriday #ichnofossil #tracefossil Feeding tracks of a soft-bodied invertebrate (Eione monoliforme) in Carboniferous sediments at Cocklawburn, Berwickshire, Scotland. The animal crawled through wet sand sieving out food particles and leaving ‘beads’ of sand in its track.

Meandering tracks of an unknown animal working the top of a beach face. The tracks consist of a series of vlosely spaced holes.

Feeding traces on an Oregon beach. Not sure who the graffiti artist is. #ichnofossil

Pie de Vaca in #Mexico "is known for its #ichnofossil record including footprints of camelids, carnivores, and peccaries, as well as the taphoglyph of an almost complete flamingo skeleton." WOW!!

Lately I've been working on identifying the various ichnofossils I collected from Kentucky last year. These I believe are Diplocraterion, got several of them.

Me pointing to numerous small fossil trackways made by a small unknown critter, which are preserved in a gray mudstone rock.

For #FossilFriday some #ichnofossil footprints left behind by some unknown Carboniferous critter (first spotted by Jason Loxton).

Diplichnites ichnofossil tracks (looks like tractor tire tracks) of a small Arthropleura (apologies for forgetting to add something for scale in photo)

A life-size depiction of what Arthropleura probably looked like and how big they could grow on display at Cape Breton Fossil Centre in Sydney Mines (I'm the one on the right...house right...stage left...)

For #FossilFriday an #ichnofossil found on beach at Joggins Fossil Cliffs in Nova Scotia: Diplichnites, tracks of Arthropleura, which is largest known land #invertebrate ever to have lived. 🧪 #PaleoSky ⚒️
