The present contribution reevaluates the fossil record of the genus Jaxea (Decapoda: Gebiidea: Laomediidae) and gives an emended diagnosis and an updated description of Jaxea kuemeli based on well preserved material from the lower and middle Miocene strata of Austria, Slovakia and Hungary. The species is distinguished from the extant J. nocturna on the basis of the tooth formula of the cheliped...

†Cratoelcana rasnitsyni sp. nov., new elcanid species, and †Pseudoacrida sennlaubi locustopsid are described from the Lower Cretaceous Crato Formation in Brazil, on basis of two well-preserved compression fossils. The genus previously comprised its type species zessini damianii whose placement is doubtful could belong to †Mimelcana UK. was only known China. pattern colouration tegmen nov. stron...

Received Accepted Ovalocephalus has a long stratigraphic range and wide geographical distribution in Ordovician peri-Gondwana. Based largely on the well-preserved specimens recently collected from China, all known forms are revised and listed. Phylogenetic analysis was conducted on the genus, involving 10 species. As suggested by the strict consensus tree, evolutional trends of the genus includ...
