Parataxonomic classification of fossil chelonian and gecko eggs

摘要: ABSTRACT The probability of fossil preservation eggs with a soft or pliable shell small thin hard layer is very poor. As result, their structural and parataxonomic classification has been almost non-existant. To fill this gap, the following groups have established: 1) for chelonian two oofamilies Testudoolithidae Testudoflexoolithidae oogenera Testudoolithus Testudoflexoolithus three oospecies, 2) gecko one oofamily Gekkoolithidae, oogenus Gekkoolithus oospecies. This paper also provides some condensed background information about amniote eggshell, its identification, parataxonomical classification, potential eggshell to fossilize.
