JamieLynn Posted January 25, 2021 Share Posted January 25, 2021 A few weeks ago, @oyo had a really interesting post about "Coral Lovers". It was a fascinating look at fossilized asexual reproduction of coral specimens - really beautiful too. I just recently brought home a bag of matrix from one of the Central Texas Cretaceous Glen Rose formation sites. And surprise surprise...I found a whole series of Orbitolina texana caught in the various stages of reproducing! So here is my "For Foraminifera Lovers" EDIT - so apparently, this is not asexual reproduction - could be merging of adults or recovering from wounding or just conjoined twins. Ah well. Still pretty cool. All orbitolinas are aprox 1/8 inch And then there's the "weird" ones - I think this one is tripleting : And this one....well, not sure what this one thought it was doing 15 www.fossil-quest.com Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted January 25, 2021 Share Posted January 25, 2021 Very interesting and nice photos. I was recently sent a bag of these myself but haven't had a look under the microscope yet. I hope I've got some dividing as well. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

oyo Posted January 25, 2021 Share Posted January 25, 2021 !!!!!! Mmmmmmm, qué chulos !!!!!!. Very interesting these little ones. Very good photos of the process. I really like the post even though I am not a forams lover. Thanks for the quote and for sharing them. Saludos Jamie. 1 Link to comment Share on other sites More sharing options...
Al Dente Posted January 25, 2021 Share Posted January 25, 2021 I think these could be healed injuries but I am not certain. Here are a couple diagrams on benthic foraminifera reproduction. 6 Link to comment Share on other sites More sharing options...
Al Dente Posted January 25, 2021 Share Posted January 25, 2021 I found an article that explains these doubled forams- 5 Link to comment Share on other sites More sharing options...
FossilNerd Posted January 26, 2021 Share Posted January 26, 2021 Whether reproduction in action, healed injuries, or abnormal growth these are still pretty cool.

Pagurus Posted January 26, 2021 Share Posted January 26, 2021 This foram forum never ceases to amaze me.

grandpa Posted January 26, 2021 Share Posted January 26, 2021 Wow some great finds, photos and inspired research. I really am enjoying this thread. 1 Link to comment Share on other sites More sharing options...
Wrangellian Posted January 29, 2021 Share Posted January 29, 2021 Interesting how similar the basic form is to Orbiculoidea, but from a totally different time period. (I was momentarily confused - had to look it up!) 1 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted January 29, 2021 Share Posted January 29, 2021 I still think it's very interesting. I have just checked through my batch of this species from the same formation and I have none like this. A few that are quite oval, but not any with this splitting/ merging / healing/ abnormality or whatever it is. Fascinating. 2 Life's Good! Tortoise Friend.

oyo Posted January 29, 2021 Share Posted January 29, 2021 The document provided by Al Dente is very interesting but I would not be comfortable with that. The article says that they are rare examples and yet you have many especimens. Article establish no less than four hypotheses for the material. I would find an expert in forams and show him those bugs to see what he said. Although the truth is that I am slightly insistent. In my village we would say "tocacojones" (). 1 Link to comment Share on other sites More sharing options...
