   Abstract : Trilobites were a successful group of marine arthropods that thrived for much of the Palaeozoic Era. Akey innovation of trilobites involved the capacity to enrol their biomineralized exoskeletons for protection; a trait that appeared early in their evolutionary history during the Cambrian Period.

4. 3. Study of the Taxonomy and the Inter and Intra Specific Variability of Phacopidae from the Lower Devonian of Algeria: Morphometric Approach and Meaning.

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Gauthier Hainaut; [2015]
   Keywords : Paleontology; Trilobite; Devonian; Biometry; Morphometry; Covariance;

   Abstract : An Algerian Phacopid fauna, described by Lemaître in 1952, is reexamined here. Species arereevaluated in order to be in agreement with modern taxonomy. To characterize the size and shape of our specimens, as well as inter- and intraspecific variations, a morphometric analysis was performed. Only holaspids were analyzed. READ MORE
