#taphonomy

I encountered the word "taphonomy" for the first time today. Basing a conjecture on its Greek roots, I thought it might refer to the law and customs pertaining to graves and burials.

My guess was wrong:

en.wikipedia.org/wiki/Taphonom

I don't mean any disrespect to paleontologists here when I say I wish my guess had been right. I suppose it's a consequence of my being less interested in the natural sciences than the social sciences and humanities.

Also, I forgot to mention this great Common Descent episode about decomposers:

🦴 Cave environments affect bone at the Galería site (Spain) over 300ka. Lowest levels <3% survival - heavy rainfall 🌧️ ➡️ acid soils leach away bone. As climate dries, preservation improves ML 🤖 89% classification Link: www.nature.com/articles/s41... #archaeology #taphonomy #geochemistry

A four-panel (A-D) conceptual model showing the evolution of bone preservation conditions in the Galería cave site across different Marine Isotope Stages (MIS). Each panel includes a cross-section of cave deposits and chemical pathways.
Panel A (GIIa, MIS10a): Shows waterlogged, acidic conditions (660-620mm/year rainfall) with extensive bone leaching and formation of phosphate minerals.
Panel B (GIIb, MIS9d): Depicts drier conditions (600mm/year) with partial bone leaching and CaCO3 migration.
Panel C (GIIIa, MIS9c): Illustrates a transition from wet to dry (560-530mm/year) with increasing alkalinity and calcite precipitation.
Panel D (GIIIb-GIV, MIS8-MIS7e): Shows cold, arid conditions (520-420mm/year) with intense calcite precipitation and fluorine incorporation in bones.
Each panel includes chemical reaction pathways shown with blue arrows, and red arrows indicate key depositional processes. The diagrams show how environmental changes affected bone preservation through time.

New #research #software is now available for download at CRAN 😁
Check it out if you want to combine ecology, #taphonomy, #stratigrapgy, and #evolutionarybiology to build your own modeling pipelines for stratigraphic #paleobiology

Very proud of this small package, which will form the basis of our upcoming workshop in Warsaw

Stepped on something on my way home and it went "crunch" and spalled into a bunch of pieces. Looked down to see what it was, and from the intact portion I could tell that it was a sandwich someone dropped on the sidewalk. #yegweather #taphonomy

I'd like to highlight a niche paper by Hans Pellmann (2021) that documents branchiopod crustacean aktuo-paläontologie--documenting what happens in the modern world BEFORE fossilization. First, a dried out community of the clam shrimp Limnadia lenticularis (photo b J. Venzlaff). #arthropoda #crustacea #branchiopoda #spinicaudata #conchostraca #taphonomy #fossilization
