I know iNaturalist isn’t especially for fossils but I know lots of users still like them, myself included. I was pleasantly surprised when this article came up in the local news today: https://www.google.com/amp/s/www.fox13now.com/news/national/giant-180-million-year-old-fossil-discovered-in-u-k%3F_amp=true
It seems like an impressive and noteworthy find that I thought maybe some people would find intriguing. I know I did. And so did the local news, apparently. And so did my son. In fact, now my son is determined to hunt for dinosaur bones himself so hopefully the next article any of you read about finding really cool and impressive dinosaur bones is about me. Fingers crossed.
