Your photos show Protozoa, Ciliata =>

possibly Calpionella, Crassicollaria, Calpionellopsis, Lorenziella, etc.

An accurate determination is only possible in thin sections in certain cross-sections, please ask experienced micro-paleontologists.

Based on my raw experience on Calpionellids:

From top left Image 1 Can be Calpionella sp., in image 2 the collar is not well preserved but it looks like to be Calpionella sp. as well, image 3 has very poor preservation, thus not determinable, in the fourth row images 10&11 are the same and I am not sure about their genus but image 12 looks like to be Chitinoidella boneti

The rest is really hard for me for determination and you will certainly need to contact calpionellid experts, however if just 10% my determinations are correct and if all samples are from the same horizon then the cooccurrences of Calpionella alpina and Chitinoidella boneti means the samples are taken from somewhere close to Late Tithonian-Early Berriasian (Cretaceous-Jurassic)boundry which should be certified by experts.

Do not hesitate to cantact one.

With my best regards

Prof. Daniela Rehakova, Prof. Silviya Petrova, Dr Justyna Kowal-Kasprzyk, ....to name a few

I must also add that the first image also is very similar to Lorenziella sp. With its short and not errect collar and small shoulders unlike Calpionella sp. that the collar is errect and shoulders are more obvious, In that case the age is Early Cretaceous (Late Berriasian perhaps) please check with experts.

Image 12 also can be Tintinnopsella carpathica
