Cool.
"Two hundred and ninety million years ago, in a mountain valley within the central region of the supercontinent Pangaea, an apex predator snapped up at least three other animals and sometime later puked up the bones."

"Thousands of years ago in what is now the Dominican Republic, there was a cave full of bones. And those bones were full of bees.
In a paleontological first, researchers have discovered that bees used the jawbones of now extinct mammals as burrows."

Burrinjuckia (Parasitology 🧬)
Burrinjuckia is an ichnogenus of bioclaustrations. Burrinjuckia includes outgrowths of the brachiopod's secondary shell with a hollow interior in the mantle cavity of a brachiopod. Burrinjuckia was probably a parasite. They have a stratigraphic range from the Late Ordovician to the Devonian. The earliest Burrinjuckia species B. clitam...

This looks IgNobel worthy. 🙂
"A recent study described something no one had ever found before: a 126,000-year-old fossilized butt-drag.
[...]
It’s funny, but it’s also profound. Because that drag line, etched into stone, tells a story about memory, behavior, and the way even the smallest creatures leave their mark on Earth."

This paper on #mudskipper tracks looks super fun for anyone else who has studied arthropod #traceFossils.
The neoichnology of a semi-terrestrial fish: mudskipper trackways in mud-dominated and sand-dominated substrates
Pretty pebble - the iron rich circular spots that run through this pebble may have been the spaces that small burrows or roots made back when this was a soft mud over 300 million years ago.

"Our new discovery, published today in Nature, details ancient fossil footprints found in Australia that upend the early evolution timeline of all tetrapods. It also suggests major parts of the story could have played out in the southern supercontinent of Gondwana.
This fossil trackway whispers that we have been looking for the origin of modern tetrapods in the wrong time, and perhaps the wrong place."
For today's #fossilfriday , here's a trace fossil, Ophiomorpha! These are the traces of burrows originally made by crustaceans. The nodules on the outside are the fossilized remains of the crustacean's faeces, which are used to strengthen the side of the burrow. This behaviour can also be seen in modern-day ghost shrimp.
These were found near the boundary of the Bearpaw / Horseshoe Canyon formations.
