3D computer modeling in micropalaeontology – Late Paleozoic conodonts and foraminifers as example Nature Precedings
Andrey V. Zhuravlev; Yadviga A. Vevel.
Three-dimension modeling of fossils is one of the branches of computer using in palaeontology. The branch has wide perspectives but it is hardly developed, especially in micropalaeontology. Proposed method of 3D modelling of microfossils demands no unique and expansive equipment and can be realized practically in any palaeontological laboratory. Lower accuracy of the models developed is not critical for most the fields of their utilization: for teaching purposes, construction of illustrated databases and virtual atlases, and for the display of microfossils to a general audience.

Ecological control on micro-ornamentation of conodont elements Nature Precedings
Andrey V. Zhuravlev.
Conodonts are considered now as specific group of early Chordata or even Vertebrata. Fifteen tooth-like conodont elements of seven morphological types compose the oral apparatus of conodonts. The elements demonstrate complex morphology. All the elements bear polygonal micro-ornamentation. The ornamentation is considered as representing imprints of the epithelium cells. Ecological dependencies of the cell sizes are known for some recent organisms.
The maximum cell sizes are characteristic of optimal environmental conditions. Thus, one can supposes that decreasing in cell imprint size in the conodonts marks disturbance in water temperature or/and oxygen content.
