Miocene instead of Jurassic: the importance of sound fieldwork for paleontological data analysis
Abstract. A diverse molluscan assemblage dominated by turritellid gastropods found in Kachchh, western India, has been interpreted in the past as Late Jurassic (Oxfordian) in age, based on associated undoubtedly Oxfordian ammonites. Recently, several investigations focused on the assemblage dealing with taxonomic, paleoecological, and evolutionary aspects. An analysis of the associated bivalve fauna, foraminiferal assemblage, and the geological context strongly suggests a Miocene rather than a Jurassic age and invalidates several conclusions drawn from the alleged Jurassic age of the fossils.
期刊介绍:
The Journal of Paleontology publishes original articles and notes on the systematics, phylogeny, paleoecology, paleogeography, and evolution of fossil organisms. It emphasizes specimen-based research and features high quality illustrations. All taxonomic groups are treated, including invertebrates, microfossils, plants, vertebrates, and ichnofossils.
