Hi all,
I noticed this weird little object on a rock in my collection from the famous Talbragar Fish Beds (late Jurassic of Australia) and I was wondering whether it might be a feathery insect antenna or just a small bit of plant. Both plants (conifers and ferns mostly) and rare insects are known from the site.
It measures only 5 mm long and I have done a quick drawing of it to show the form easier. Note the double branching tips on the lower filaments.
Cheers!
