Jose Serna Posted March 3, 2021 Share Posted March 3, 2021 I've found this about 50 miles from the Caribbean Sea in Colombia, in a cut made to a hill for a highway to pass through. The layer where I found it is almost vertical. I've looked and found similar shells in the web, but no one has the same grooves. Can anyone help me? Found near 8.531326033223863, -75.68011324026482 Link to comment Share on other sites More sharing options...
jpc Posted March 3, 2021 Share Posted March 3, 2021 Buenos dias- The first step would be to find a geological map of Colombia to see what age rocks are at this site. I am amazed that your GPS goes to this many digits. That must be down to the micron. Link to comment Share on other sites More sharing options...

Plantguy Posted March 6, 2021 Share Posted March 6, 2021 (edited) Looks like its Mio-Pliocene 7-3.6 MYA in Age in that area, maybe the El Cerrito formation. Just guessing but maybe its one of the Turritellidae. looks like its incomplete..any chance the aperature/opening to the shell is present or is it broken/sheared off? I cant help further but someone else might... Regards, Chris Edited March 6, 2021 by Plantguy spelling edit Link to comment Share on other sites More sharing options...
