    Puerto Rico fossils

    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 th

    Conglomerate fossil bone puerto rico

    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.
  3. If someone knows the common or scientific name of this shell embedded in the rock or the other ones, please let me know. Thanks.

    Fossil snake or worm?

    Hello, I found this peculiar stone and noticed it had something fossilized to its core, what on earth is it? I took the best pics I could. It was found in the san sebastian creek formation in Puerto Rico. San Sebastian Limestone.
  6. Hello everyone, I'd like to share my extreme budget collection of exotic megs/shark teeth so far, I've have been collecting shark teeth and other for a little over a year and a half now on an extremely tight budget and have been surprised by what I was able to get a hold of so far. Condition doesn't bother me hence the budget but I have been able to find some megs from from interesting locations over the short period of time I've been collecting with a little bit of luck. Locations include Puerto Rico, Cuba, Japan, Hawaii, Morocco, Mexico, Peru, and The Phillipines. Anyone else out

    Unidentified fossilized wood

    Hello, I came across what seems to be a fossilized branch of an unidentified plant or tree, it looks similar in texture to my other fossilized wood so i recognized it and picked it up at a riverbank in Puerto Rico. What type of wood is it? Any answer would be highly appreciated
  8. 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.
  9. I found this at a river at puerto rico, is it a fossilized crab claw? What type of crab is it? What era is it from?

    San Sebastian Limestone

    So I went to this river thinking i was going to have a blast cannon balling into the deepest areas except I found an excellent specimen and spent the rest of my day collecting amazing fossils.
  11. GallinaPinta


    So I only have the faintest idea of what this could be. I vote for the oyster crassostrea since that's what I was told. But now someone told me it was a rudist and im a bit confused. Could it be cretaceous?

    Thylechinus or Echinometra?

    So I found this specimen by the river in san sebastian and according to https://www.jstor.org/stable/1301379?read-now=1&seq=5#page_scan_tab_contents it could be either Echinometra lucunter or belonging to Thylechinus. Both of these specimens (supposedly both specimens have only been found once in Puerto Rico) look alike so much according to my recent searches that im now more confused than ever. Any expert out there who can help?

    Megalodon tooth from Puerto Rico

    Hello everyone, I'm visiting my family in Puerto Rico and I met a person who has this megalodon tooth for about 20 years. The location where the tooth was found is in Moca Puerto Rico a non coastal area but with the same limestone formation like the coast. I have until the 28 of this month to convince that person to sell me tooth before I go back Texas, so I wonder if anyone has a good idea a meg like this from a very rare location can worth.
  15. So the beach was recently excavated and what was covered by the ocean for so many years, dried out and the sand was excavated and made into huge dunes full of old seashells and mysterious oysters and conches. I found many bivalves and i stumbled upon this weird stone that is covered in fossil like formations and shells. Any idea what it could be? Is it a fossil? Is it extinct? Its driving me NUTS.

    My fossil and mineral collection

    The shells and other sea stuff was collected last summer in Puerto Rico while visiting my family 2 months before the hurricane Maria devastated the island .
  17. So after hurricane Maria at Puerto Rico, I got curious about the small river down the mountain of my backyard so I went down to explore it. To my surprise some boulders tumbled down due to a soil erosion so I started exploring the scene. I found a few rocks that are actually some very peculiar fossils. The thing is that I don't know anything about fossils in PR so I'm going nuts trying to figure it out! Is it some kind of fish? But it's too big to be a fish and the bone-like structure is quite solid. Professionals and expert paleontologists, please help!
  18. Hello all, I was cleaning off the matrix off a bivalve I found some time ago in a the Guajataca River in northern Puerto Rico. This is a sample of shaley clay from the San Sebastian Formation and dates back to the middle(?) - upper Oligocene I was wondering if anyone would be interested in the matrix I cleaned off. it's a small sample ~4.0 grams of matrix. I can ship it to someone in USA that wants to look at it and see if they find anything interesting micro fossils. If any one else is interested let me know, I can eventually ship some more mat

    Gastropod ID?

    Hello, I found this Gastropod while hammering a chunk of Lower Miocene Limestone at a beach in Northern Puerto Rico. In my opinion it's a nice fossil with some crystallization. The Description from the USGS on the limestone formation is: Hard granular calcarenite overlain by alternating beds of chalky marl and rubbly limestone Just wondering if any one could help me ID it. Thank you!
