For Foraminifera Lovers


JamieLynn

Recommended Posts

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" :ighappy:

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

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.

!!!!!! 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.

I think these could be healed injuries but I am not certain. Here are a couple diagrams on benthic foraminifera reproduction.

Whether reproduction in action, healed injuries, or abnormal growth these are still pretty cool. Thanks for sharing! :)

This foram  forum never ceases to amaze me. Thanks for sharing your wonderful, unusual finds, Jamie, and for the fascinating research report, @Al Dente

Start the day with a smile and get it over with.

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!)

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. :)

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" (:D).
