Cavernbook: a cavern where everyone chisel his/her photo and his/her thoughts

Dogs seem to like me so maybe I'd be one of the first to domesticate dogs. I'd probably just live with dogs.

Navigation and being the first to try a cool looking mushroom and findout how dead I get.

Oh! I'm actually somewhat decent with some useful things. I got sent to a wilderness school for fuck up kids when I was a teen. So I know how to, and have applied a lot of survival stuff.

I know how to effectively make a somewhat permanent shelter. I can make and use a bow drill to make fire, and along the same principal but with much more effort and time I could make fire with hand drill or fire plough techniques. I know how to make basic traps. I can make cordage, and have very, very very basic tracking skills. I know some edible and toxic plants in my area (not exhaustive by any means). I know how to clean and dress game. There's a lot of other stuff, but those popped into my head immediately.

It's been a long time since I've done all this, but the knowledge and know-how is all there. I'd actually be a decent person to have around!

obsessing over plants and accidentally dooming the world with agriculture

Time travel, evidently.

Foraging for plants.

Butchering, I live on a farm and butcher sheep/lamb and chicken is second nature to me ( started when I was 12 )

i'm a fairly deft hand at pottery. i'm also decent at fiber crafts. depends when and where during the stone age, of course, that's a pretty big expanse. if i'm really lucky, i'd be in one of the many cultures with special spiritual roles for trans folks. i've also got good rote memorization skills, so i can help with oral history.

Cave wall art. Carving trinkets and talismans. Might branch out into making spear tips, arrowheads, axes, stuff like that.

Everyone alive right now must have ancestors who very literally did live & survive though the stone age and the ages before and after that. Wish I knew what my ancestors did to survive stone age, or better still if I could like watch them in a time lapse video. I guess I might have run away from stone lifting to go be a shepherd or something.

Fucking, for sure

Bronze peddler. "Hello, have you heard of bronze? Just attach it to your axe instead of stone. No more annoying stone chopping! And look, it's shiny!"

Absolutely nothing lol. I do tech support for a living and work on cars as a hobby.

Knapping.

Wait, I mean napping.

I can make soap from fats and lye (from wood ash). Getting the right balance of fats/lye would be tricky; I've never used wood ash so I'd need some time to work out the right formula. But, theoretically, I could make handmade soap for everyone.

Juggling. I'd find some nice stones or pinecones and teach everyone how to juggle and do some tricks. I also know an ancient game you can play with stones or knuckle bones. And I know some songs. And stories. People in the stone age had lots of free time to pass, so all of these would come in handy.

Feeding the living with my body

Criticizing people about their hair styles

Reaching things on top of the fridge would be my special skill. I hope they'd create a special government position just for people like me.

hoardlng stones

Being that person providing a better method halfway through a process. A cave person standing on top of another to cave art the ceiling? Halfway through I go "...You know you coulda just grabbed the log from outside, leaned it against the wall and climbed it". Someone halfway through whittling a bowl? "Oh, yeah, I saw some coconuts on the beach they'd be perfect".

I have the great hobby of Looking At Random Things, but the bad habit of assuming everyone else saw those things too so they must be doing what they're doing for a reason lol. That all said I'm sure I'd be dead from dysentery within a week or smtg, they wouldn't have to suffer me long.
