Hello, I think I found my first serious fossil!! Up until now, I always found invertebrate and plant fossils like echinoids and giant oysters, but recently after fossil hunting last week at my favorite spot, the San Sebastián Limestone, I stumbled upon something absolutely incredible. I was rushing to get home cause it was getting dark and the river was getting pretty cold, but I tripped over this huge stone. I saw the shadow of something stuck and quickly put it in my backpack, swam and crossed the river and bought it home thinking it was some kind of fossilized wood. It is very, very heavy. However, after checking it closely, it looks like it's actually a bone! Those are extremely rare in the island and I've never seen one, so I'm hoping some bone experts can help me properly identify this fossil.

I want to share this amazing experience. This was in San Sebastián, Puerto Rico. The Gozalandia waterfall is one of the most beautiful spots in the island, and because of this, it is a tourist attraction. I always fossil hunted near but I never went to this specific waterfall. I live close by so I went to take a simple dip but I absolutely could not hold back the urge to fossil hunt as soon as I got here. It is absolutely beautiful! After going down the wooden stairs, I immediately started checking out the rock beds. There's even a cave under the waterfall! After just 30 minutes of checking the stones, I found a beautifully preserved echinolampas. This formation is known to preserve fossils from the oligocene and paleogene period according to https://en.wikipedia.org/wiki/List_of_fossiliferous_stratigraphic_units_in_the_Caribbean#Puerto_Rico and San Sebastián has been my favorite spot to fossil hunt. I always find many beautifully preserved specimens.

I found this bone in the san sebastian limestone, in Puerto Rico. I always find interesting fossils there, but this is the first bone I collect. There have been skeletons of extinct sirenia found in this exact same place, so maybe it could actually a fossilized bone from an extinct species. I have no clue when it comes to bones though, so an expert is highly apreciated.
