I found it in the first few centimeters of Adriatic coastal lake sediments (Ba_ina Lakes).

Interesting - I presume those are modern or Holocene sediments? Do you have photos?

This species is very common for restricted, shallow and alkaline environments of Miocene to recent sediments. I'm going to take some pictures for You of modern sediments (try to do my best with it) and would emailed with upper Miocene pictures.
