New discovery! Here @mariaguagnin.bsky.social and our team report on 12,000-year-old life-size camel rock art engravings in the Saudi desert. #GreenArabia @griffith.edu.au www.nature.com/articles/s41...

Was great to present a poster at #ESHE2025!

I commissioned it from Thalia Nitz Illustration!

While risk aversion can have short term benefits, this will limit long term skill acquisition and technological ceilings. We suggest that late Acheulean handaxe forms required tolerance of greater learning costs via deliberate practice, indicating 'mental time travel' and social support for learners
finnstileman.bsky.social
Simply, novices should cease knapping soon after a cutting edge is established, with further attempts at shaping tools tool increasing risk of a poor functioning tool. The novice rough-outs are similar in attrivutes to early Acheulean handaxes from Ubeidiya, which could reflect similar risk-aversion
finnstileman.bsky.social
Additionally, novice handaxes were more likely to break before completion, happening for 26% of attempts by novices and 7% for experts.

Edge crushing was recorded from handaxes and was three times higher on novice tools (1/3 of circumferences). Crushing % negatively correlates with rate of successful flakes for novices but not for experts. This indicates that knapping errors can be reversed by experts but they accumulate for novices
finnstileman.bsky.social
Recorded sequences of successful flake removals and mistrikes show clear differences between expert (top) and novice (bottom) knappers. Mistrike rate rapidly decreases for novices, outnumbered successful strikes by the end of the rough-out stage.

A PCA analysis of 3D shape and morphometric data show that expert handaxes improved much more than novices' from rough-out to final stages. Showing greater value of continued knapping for experts
finnstileman.bsky.social
We recruited 10 expert and 10 novice knappers, asking them each to replicate 4 flint handaxes, mimicking a target form. We 3D scanned handaxes as starting blanks, rough-outs (i.e. a biface prior to shaping) and finished forms. Flaking Sequences were also extrapolated from experiment footage.

Happy to share the first paper from my PhD! Open access in a special issue of JAS, 'The Mind in Deep Time: Interdisciplinary explorations of cognitive evolution'

When less is more: risk, reward and optimisation in Acheulean handaxe manufacture and the impact of skill

As the most numerous manifestations of technology across the Palaeolithic record, linking stone tool artefacts to past hominin cognition and expertise…

More ceramics! So fun to work with!

Picked up a stone-textured dish at a pottery market that perfectly nests a porcelain handaxe; makes me think of the tool latent within a nodule before being shaped to fruition

#Neanderthal Fat Factory!
V. exciting to see new, massive evidence of this grease-rendering behaviour which we've long believed was going on.

(someone once commented I use the word "fat/fatty" a lot in the narrative/poetic sections of #Kindred, THIS IS WHY)

My latest weekend pastime has been to model clay replicas for my little museum! Particularly fond of the Neanderthal (La Ferrassie 1) skull!

Finally got round to finishing this drawing of a 300,000 year old #handaxe from Stoke Newington, London, found by S.H. Warren in 1894. Now this little-un, along with others from Stoke Newington that I've drawn, lives at the British Museum

And here's the scan from the same handaxe! A razor (tranchet sharpened) tip!

Spent the day with master flint knapper, John Lord, to 3D scan handaxes. Some were made by him, but this one was collected from a quarry spoil heap at Lynford and dates to 65,000 years ago! Fresh as the day it was made!
