It was some time ago that I read of that, so the details are fuzzy. And here’s what I found:

“A 10,000-year-old engraved stone could be a lunar calendar. The rare pebble — found high up in the mountains near Rome, Italy, the hammer-stone was found on top of Monte Alta in the Alban Hills. It’s believed that our early ancestors would’ve used the stone to keep track of the moon’s cycles. Notches were engraved “as if they were being used to count, calculate or store the record of some kind of information. And these notches — which total either 27 or 28 — suggest the stone’s engraver used the pebble to track lunar cycles.” ref

Friends, spicy foods are no joke!
How many bananas in a DeVito?
By the simple minded notion of my sense of humor. ;-) Any more hares you’d like to split?
I wonder if seagulls experience love, they’d be the most likely candidates. Hmm…
LoL, indeed it’s not tho’, it’s the Great Black-Backed Gull. Damn those taxonomists!!!
My whole point of posting was to point out how inane, and pedantic the distinction between Gull and Seagull actually is, which is the distinction that OP made. And of course on the Fediverse that generated a whole lot of conversation, including this sentence.
Wait, but which is it? Tequila or Gin? I need THE SCIENCE!!
