A Wolf incisor from Repolust cave Austria. This is believed to be about 300,000 years old. It’s the oldest known piece of jewellery there is, made during the Heidelbergensis occupation of Europe.
I got this from a great paper on paleoart objects, so this is probably going to be my subject for the week. One thing that’s become abundantly clear from reading it is that Homo Erectus and Heidelbergensis were behaviourally very similar to us, at least in their fondness for art and jewellery.
