Automatic identification of conodont species using fine-grained convolutional neural networks
Frontiers in Earth Science, 2023 Conodonts are jawless vertebrates deposited in marine strata from the Cambrian to the Triassic that play an important role in geoscience research. The accurate identification of conodonts requires experienced professional researchers. The process is time-

Revision of the conodont zonation of the Wenlock–Ludlow boundary in the Prague Synform [PDF]
Estonian Journal of Earth Sciences, 2014 The regional zonation of the Wenlock–Ludlow boundary is established for the Prague Synform using refined data from updated conodont records. The following conodont zones have been recognized in the Prague Synform: the Ozarkodina sagitta sagitta Zone, the
