a total of 12 species of marine gastropods, among which two taxa are new, is reported for the first time from the miocene deposits of khavich section, south of sirjan, kerman. gastropods assemblage in khavich area indicates deposition in shallow, warm ramp-type carbonate platform. the miocene and even oligocene gastropod assemblages, relatively similar to khavich section, reported from the othe...

Abstract Centennial- to millennial-scale climate variations are often attributed solar forcing or internal system variability, but recognition of such in the deep-time paleoclimate record is extremely rare. We present an exceptionally well-preserved, millimeter-scale laminated marlstone from a succession precession-driven limestone-marlstone couplets deposited Western Interior Seaway (North Ame...

A total of 12 species of marine gastropods, among which two taxa are new, is reported for the first time from the Miocene deposits of Khavich section, south of Sirjan, Kerman. Gastropods assemblage in Khavich area indicates deposition in shallow, warm ramp-type carbonate platform. The Miocene and even Oligocene gastropod assemblages, relatively similar to Khavich section, reported from the othe...

Sequence data derived from four markers (the nuclear RP1 and Aldolase and the mitochondrial 16S rRNA and cytochrome b genes) were used to determine the phylogenetic relationships among 32 species belonging to the genus Hippocampus. There were marked differences in the rate of evolution among these gene fragments, with Aldolase evolving the slowest and the mtDNA cytochrome b gene the fastest. Th...

We have assessed for the first time the phylogenetic relationships and biogeographic history of the crabs of the genus Maja that inhabit European coasts: M. brachydactyla, M. crispata, M. goltziana and M. squinado. Using mitochondrial markers, we have recovered a well-resolved phylogenetic tree that supports a single origin for the European species, most likely from an Indo-West Pacific ancesto...

The Central Iran Basin is a region with unique environmental characteristics in which the Late Paleogene–Early Neogene benthic foraminifera display distinctive distributions and abundances that can assist identifying intervals best reservoir potential. Lipidocyclinid miogypsinid zonal marker taxa this be correlated those SBZ23 (European Basin), indicating an Oligocene (Chattian) age. With sedim...

Abstract The spider crabs Willinachoides santanai n. gen. sp. from the early-middle Miocene of north Brazil and Paradasygyius rodriguezi late Venezuela are described illustrated. Additionally, Eoinachoides senni Van Straelen, 1933, Oligocene–early Venezuela, is redescribed based on photographs holotype, diagnosis latispinosus Carriol, Muizon, Secretan, 1987, Peru, emended also basis holotype. p...
