Found on beach of Turks and Caicos. Not entirely sure if it even is a fossil. 14cm tall, 6.5 cm at widest point. Lmk if need any other info

Hi all, For a few months now, I occasionally go searching for shark/ray teeth in an old industrial area in Aruba. I found hundreds of smaller shark teeth (probably carcharhinus) and a handful of very cool & much larger teeth (likely otodus angustidens). This morning, I went walking the dogs there and stumbled upon a chunk of a much larger tooth! Could it be the megalodon? it could be a larger specimen of an O. Angustidens but the proportions are not quite the same… I'll let the experts judge for themselves. The (almost) complete O. Angustidens tooth in the middle is 2’1 inches (5,3 cm) long.

The Crocodilians (Crocodilia) are a resilient group of reptiles, with the order originating around the Late Cretaceous 95 million years ago and still very prevalent globally in many aquatic ecosystems. But it was not too long ago that this group was even more diverse. Though way more diverse between the Paleocene-Pilocene eras between 64-2 Million years ago, the Crocodylomorpha (mainly Crocodillians) were still fairly diverse during the Pleistocene-Early Holocene eras - more diverse than they are today. This lack of diversity today is mainly due to the climate change that occurred between the Pleistocene and Holocene and (Unfortunately) overexploitation by Humans. Human induced Climate change since the Industrial Revolution and direct overexploitation by people still plagues many crocodilians today. It is only because of global Conservation efforts that some of the most endangered crocodilians today have a fighting chance at survival. I've decided to make a quick list of the unique crocodilians of the Pleistocene-Early(to part late) Holocene which can hopefully demonstrate the diversity of these magnificent animals during this time. Let me know if I forgot any examples. Australia - Quinkana fortirostrum (Pliocene-Pleistocene) Possible Unnamed Quinkana sp. (Possibly Q.fortirostrum) (Queensland Museum Specimen QM F57032) (Note: Quinkana could have grown to between 10-20 feet in length) Paludirex vincenti (Pliocene-Pleistocene 5.3-0.012 years ago) (Note: Plaudirex species could grow up to 4 meters (13 feet) in length) Paludirex gracilis (Pliocene-Pleistocene 5.3-0.012 years ago) (Note: Plaudirex species could grow up to 4 meters (13 feet) in length) Gunggamarandu manunala (Pliocene-Pleistocene 5-2 Million years ago) (Note: Gunggamarandu manunala could have grown up to 7 meters (23 feet) in length) Japan - Toyotamaphimeia machikanensis (Pleistocene 0.8-0.1 years ago) (Note: Toyotamaphimeia machikanensis could have grown up to 7.7 meters (25 feet) in length) Taiwan - Unnamed Toyotamaphimeia sp. (Pleistocene 0.8-0.1 years ago) China - Hanyusuchus sinensis (Early-Late Holocene (up to the 1400s A.D. around 600 years ago)) (Note: Hanyusuchus sinensis could grow up to 6 meters (19 feet) in length) Africa - Euthecodon brumpti (Pilocene-Early Pleistocene 3.5-0.781 Thousand years ago) (Note: Euthecodon brumpti could grow up to 10 meters (33 feet) in length) Crocodylus thorbjarnarsoni (Pliocene to Pleistocene 5.3-1.8 Million years ago) (Note: Crocodylus thorbjarnarsoni could grow up to 7.6 meters (25 feet) in length) Crocodylus anthropophagus (Pleistocene 1.845-1.839 Million years ago) (Note: Crocodylus anthropophagus could grow up to 7.5 meters (25 feet) in length) Madagascar - Voay robustus (Late Pleistocene-Holocene 0.1-0.01 years ago) (Note: Voay robust could grow up to 5 meters (16.4 feet) in length) Thailand - Gavialis bengawanicus (Early-Middle Pleistocene) Indonesia - Gavialis bengawanicus (Early-Middle Pleistocene) New Caleodonia - Mekosuchus inexpectatus (Holocene 0.012-0.004 years ago) (Note: Mekosuchus species could grow up to 2 meters (6 feet) in length) Fiji - Volia athollandersoni (Late Pleistocene-Early Holocene) (Note: Volia athollandersoni could grow up to 3 meters (10 feet) in length) Vanuatu - Mekosuchus kalpokasi (Holocene 0.012-0.003 years ago) (Note: Mekosuchus species could grow up to 2 meters (6 feet) in length) New Guinea - Murua gharial (Ikanogavialis papuensis) (Late Pleistocene-Early Holocene) What do you guys think?

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’m not sure if this is allowed as a one off post, but I’ve been trying to identify this Echinoid I found in Turks and Caicos and I can’t find a species name and I was wondering if anyone knew it, thanks it’s a beast

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.

I have found these teeth pve a period of time. I know they are terth but for what creature, i haven't a clue. Ant thoughts would be appreciated.

I have this beautiful colored Caribbean Megalodon tooth , the blade and serrations are nearly perfect, but it has bourlette, and root damage. Not sure if I should have the tooth restored, or leave it natural. I even thought about making a pendant out of it. I would love to hear some of the members opinions. Tooth is 3.75” as is.

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.

Although fossil finding was not part of our vacation itinerary, fossils found us. After our boat docked outside of the strip just outside the town of Montego Bay, there was a large shelf of limestone filled with coral fossils. I had just been snorkelling in the living coral reef at Secrets Bay, and it was fabulous to see corals in living colour with all those abundant tropical fish eddying about. The limestone here dates between the Mesozoic and Cenozoic, and is largely dominated by coral. Some of the specimens in the rock have very nicely defined corallites. As I didn't think to bring a rock hammer on vacation, I did manage to find a loose rock to hack out a few small specimens. This first batch shows these corals in their raw, in situ context:

Have no idea what this is

Hello this is my first participation in this forum. Around 30 years or so, my father and I had found this strange rock. I would appreciate if anyone shares any type of information. Thanks!

Hi colleagues and friends, I have been findind and often collecting tose eye catching elongated fossil corals on the Hispaniola island, like "Pirouline's rolled wafers". They have a cavity inside on mostly case and have up to 3 inches diameter I guess. As I'm not very familiar with these coral fossils, can you please help me to ID these fossilized corals and comment anything about the environment, ages, behaviors, occurrence, distribution, etc. Thanks a lot for youn kindly help colleagues!

Came across this paper published last year, apologies if it's already posted. Located in the Falcon State of Venezuela the Urumaco formation provides a good look at the Sawfish and other elasmobranch Assemblages of the South Caribbean in the late Miocene, in an area that gets very little notoriety.

Hello, I found this item on a recent vacation, and I was hoping for some help in identification, since my travel partner and I disagree on what it is (rock vs. tooth). Location: Sandy beach in Aruba (Caribbean island north of Venezuela). Size: Longest dimension is about 5 cm, as shown in the photos. Photos: Front: Rear: Side: Any help is greatly appreciated!
