This fossil was found by a kid on the Pacific foothills of the Talamanca Mountains, Costa Rica. Between San Vito and Buenos Aires. Trying to sort out what it is.

Found near Quepos on the beach. Not sure if it is petrified wood or not? Thx

Found this on the pacific coast of Costa Rica, I know it’s not rare to find teeth on the beaches here however this has been weathered down so it’s smooth. Me and my friend are in a debate about what it is so any opinions or validations would be appreciated. I personally think a very old meg tooth

Costa Rica beach find.

My 7 year daughter found this fossil in a river in Costa Rica. I am not sure if it is old. I think is a Bovidae tooth. Could you help me with identification? Thanks!!

I found this fossil on our property in Puriscal, Costa Rica. I found it on the ground after moving some dirt from the berm next to a ditch. This ditch was dug by hand for us several years ago. The previous owner backhoed this area to flatten it. but couldn't go any farther due to the enormous rock. I am posting here because I want opinions if this is petrified wood, or bone. It measures about 10cm long, diameter about 8cm. There is a crystal formation on one end.

Was recently in Costa Rica and found these on the beach. Have found many black sharks teeth in the Carolinas but wasn’t sure if these were also? Any info would be greatly appreciated. TIA

Was on holiday in costa rica 6 months ago and found this on the beach at the end of a small estuary. I guess it washed down to the beach, I'm pretty sure it's no aquatic animal tooth and I'm not even sure if it's a tooth. My only guess was crocodile but not even sure on that theres no look of enamel. Possibly a bit of bone that's been weathered into this shape. Any ideas? Struggling to add pictures because of the size limits The piece is around 2.5 inches long 1.25 inches wide

Hey everyone, this is is my first post, and I am not a fossil expert by any means. Yesterday I found this bone on the beach, and I'd like to find out what it is. I am on the Southern Caribbean coast of Costa Rica.

Hi there, I know very little about fossils but on a recent trip to the Caribbean coast of Costa Rica I stepped on a small tooth in the sand. Without thinking I assumed it was shark due to where I found it, but looking at it I then thought it was a dog's tooth, but it doesn't look like that either. It's white and extremely porous, it was found at the top of the beach on top of the sand so it was probably baking in the sun for quite some time. The beach is not often frequented by people, it's a remote area of the country, but there are stray dogs in the area and it's known to be shark infested waters. I don't know anything but I've been looking at pictures of teeth for an hour and a half and I'm stumped, so any help would be appreciated.

Hi all. Im sure this is common and boring, but just a bit curious about what I found on the beach in Costa Rica. It measures about 2" each way. Shark tooth? It is totally a rock now. Thanks

hello there I am an enthusiast of geology and paleontology, I wasexploring some sites of my country for wood fossil, and others.

While on vacation in Costa Rica in 2009, I spotted some fossil shells in situ and am hoping someone might know their age or formation. The site is called Playa Limoncito, on the Pacific coast of Puntarenas province a couple of miles south of Tarcoles. The tour guide was aware of the fossiliferous rocks along the beach, but he didn't know how old they were. The exact species are probably unidentifiable from the cross-sections, but I am hoping that someone might know what geological formation is exposed or the approximate age.

Just returned from the wonderful country of Costa Rica. The trip was to celebrate my grandmothers 80th birthday! Being this was a family trip, I had limited time for any "back country" explorations, missing too many suppers would not have gone over well!! So I decided I would take day trips to as many beaches as possible, and consider all info collected for a future trip if anything really caught my eye. We were staying in a villa in Manuel Antone. I walked the local beaches all the way up to Quepos and paid special attention to low tide coral that would trap anything washed up. The current runs north there, so I focused on areas where the land hooked outward to catch the most debris. Beautiful sea shells, mullusks with opalesque interiors and coral were aplenty, but that is not what I was after. After 2 days and a good burn all I found fossil wise was what looks to me like horned coral encapsuled in a light green limestone. I also came across some small chunks of agate that I will have to cut n polish at a later date. I felt I had exhausted my search, and had little reason to believe these finds were deposited by any nearby rivers. So I took a bus ride south down to a little surfing village called Dominical. The beach was all tumbled river rock and driftwood. I had lost my boots on a prior drunken evening and was stuck wearing my girlfriends pink walmart beach shoes... Brutal on the feet!!! I rented a surfboard as the waves were pretty nice, and there was plenty of room in the line up to partake. My cash was in a ziplock bag which I brought out surfing, but due to thieves, I had to bury my cigs and lighter under some rocks, and used some driftwood as directionals to find in the future. While squirreling away my possessions I dropped a piece of burnt driftwood on my rock pile to help cover my stash when I noticed something... The sound was all wrong!! There was no thud, but a high pitched clack!!!! Sure enough, I had myself a piece of petrified wood!! I surfed to my hearts content, and decided to do some investigating. There was more pet wood, not in abundance, but enough to think the source was nearby! When it began to rain I noticed jasper nodules too. I showed the wood to a vendor who was working on a wire wrap necklace. He said its from the river to the south!! This led to 2 fundamental problems, 1- lack of time, 2- a good potential for crocodiles! I had seen my fill of crocs there already, some locals would feed them chickens for tips from tourists... They are quick!!!! They are mean!!! And I'm in their house!! I decided I will have to return in the future for a surfing/digging trip. I have a local guide set up for the river, he wants the wood for jewlery. I promised to teach him how to set up cheap lap saw/ polishing units so he didn't have to pay someone else for cutting his jewlery. Airfare is cheap after the new year. I'll pick up on this thread later!!!

I will be in Quepos Costa Rica next week. I have heard there are an abundance of shark teeth along the pacific coast. I have checked for prior postings on this forum but I did not find many leads. Google searches have given some Info, but again, not much besides claims owned by universities. Any info would be appreciated! Thanks!
