Eyepiece Lens -this is the part of the microscope that has the ocular -lens which the user looks through to see the magnified specimen. The efficiency of traditional sample manually selecting with microscopes is quite low and hinder the discoveries of new species, thus recognition and classification of microfossils by artificial intelligence (AI) is substantially in the request. Pamela Gore Rads have always been marine and all, as far as we know, are planktonic. Many require special techniques of removing them from rocks or making them visible, others require very specialized equipment for their study.

Q: Refer to the vertical cross sections in Geologic Cross Sections 3 and 4 on page 224 of the Laboratory Manual (Activity 8. Large-scale mass spectra sampling allowed the construction of binary classification machine learning (ML) models, which can be used for the identification of microfossils from other Precambrian cherts and other rocks (once calibrated), where morphological integrity of the putative microfossils is lost, thus providing a way to assess biogenicity . The single-celled forms help to develop and test evolutionary models using organisms that are not multicellular or sexual in all cases, and with greater ecological variety.
