dinosaur man Posted March 12, 2020 Share Posted March 12, 2020 Hi I’m wondering if these are Tube Corals? I have a lot and found them in rocks and sand around my resort in Punta Cana, Dominican Republic, not to far from where I found my fossilized crab claw. Link to post Share on other sites
Tidgy's Dad Posted March 12, 2020 Share Posted March 12, 2020 Possibly the burrows of something? 5 Link to post Share on other sites
abyssunder Posted March 12, 2020 Share Posted March 12, 2020 I suppose they are ichnofossils, something like the houses constructed by decapod crustaceans. 4 Link to post Share on other sites
Fossildude19 Posted March 12, 2020 Share Posted March 12, 2020 I wouldn't discount root casts. 5 Link to post Share on other sites

Troodon Posted March 12, 2020 Share Posted March 12, 2020 Not my area of expertise but check this out. Followed up on Tim's comment So recent root casts? https://www.researchgate.net/publication/223888096_A_physiological_mechanism_for_the_formation_of_root_casts 6 Link to post Share on other sites
dinosaur man Posted March 13, 2020 Author Share Posted March 13, 2020 Thank you everyone!!, I’m not sure if it’s mangrove roots or some type of other plant or possibly something totally different. But i will clean them up and see if I can find anything that might help. Link to post Share on other sites
supertramp Posted March 13, 2020 Share Posted March 13, 2020 I would say rhizoliths, don't know if fossil or recent https://www.google.it/search?q=rhizoliths&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiYi6SZj__XAhUIxRQKHfvCD8wQ_AUICigB&biw=1517&bih=707 ciao 2 Link to post Share on other sites

abyssunder Posted March 17, 2020 Share Posted March 17, 2020 Pictures (in situ) may help a lot. Each one of the proposed variants might be true in the existing contex. My feeling say burrows, but I could be wrong. I have similar specimens from the Miocene of Romania where no plants were present. 1 Link to post Share on other sites

I have similar specimens from the Miocene of Romania where no plants were present. Sadly I don’t have a photo of them in situ, but if it helps I found two in this hill area imbedded inside it. And to other around a half a km of the beach at my resort in an area that was covered with hard rocky sand and plants around it but the plants where to far away for it to be something to do with an modern plant, so with this I’m thinking it’s probably not modern what ever it may be. The hill where I found two of the specimens imbedded. Link to post Share on other sites

I have similar specimens from the Miocene of Romania where no plants were present. And also they could be burrows from crustaceans like you said above, because I found what most likely a fossilized crab claw near the two specimens. Link to post Share on other sites
