Al4galm Posted July 10, 2018 Share Posted July 10, 2018 Hi guys, I am not even sure if this is the correct place to ask, but lets give it a try. This past weekend I visited my hometown, Tampico in Mexico (right in the center of the Gulf of Mexico). It is a beach town, and it also has a big River that goes into the ocean so it has been a major port for many years. Recently the local governmet decided to do some maintenance on the beach promenade. A bunch of big rocks were moved from the Tamuin area (112 kms west from Tampico) and basically dumped along the promenade to contain the waves. The rocks have many shapes on their surface and different colors. I am extremely curious to find out what they are, but being an accountant I am absolutely clueless. If anyone knows what these are or can direct me to another forum where I could ask please please lemme know. Link to comment Share on other sites More sharing options...
abyssunder Posted July 10, 2018 Share Posted July 10, 2018 Welcome to the Forum! I see rudists in natural (weathering) sections. They are pretty nice! link 6 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Most of Your pictures do show fossil shell. Others will let You know what types. (I am not much good with shells). Darwin said: " Man sprang from monkeys."

Innocentx Posted July 10, 2018 Share Posted July 10, 2018 Except for picture 5 (persistent lichen or maybe pyrite), you have some lovely fossils. @abyssunder is correct about the rudists. 1 "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...

You may be correct. I skipped picture 5, because I haven't seen fossils there.

Ludwigia Posted July 10, 2018 Share Posted July 10, 2018 I agree with rudists, colonial bivalves which existed during the Cretaceous period. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Auspex Posted July 10, 2018 Share Posted July 10, 2018 Rudists were odd reef-building clams; yours are very attractive display specimens.

abyssunder Posted July 10, 2018 Share Posted July 10, 2018 As far as I can recognize the shapes of them, you have caprinid rudists, maybe Caprinuloidea, Caprina, Kimbleia, or similar. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Al4galm Posted July 10, 2018 Author Share Posted July 10, 2018 Yay! Thank you so much!!! My 5 year old is going to go bunkers when I explain to her what those are. I asked and the rocks were from a quarry called "El Abra" in San Luis Potosí. Will try to get in contact with the local authorities, having a description of what they are can be super interesting. Sadly, nobody was paying attention to them. 1 Link to comment Share on other sites More sharing options...
abyssunder Posted July 11, 2018 Share Posted July 11, 2018 I supposed they are from the El Abra.Thank you for the confirmation.
