ABSTRACTThe study of drilling predation has been largely limited to molluscs. Herein, we report drilling predation on Recent acorn barnacles by gastropods from Chandipur, eastern India. The aspects...

Turritellid gastropods are important components of many Cretaceous—Recent fossil marine faunas worldwide. Their shell is morphologically simple, making homoplasy widespread and phylogenetic analysis difficult, but fossil and living species can be recognized based on shell characters. For many decades, it has been the consensus that the oldest definite representatives of Turritellidae are from the Lower Cretaceous, and that pre-Cretaceous forms are homeomorphs. Some morphological characters of th...

ABSTRACTDrilling predation provides a rare opportunity to study and quantify prey-predator interactions in the fossil record. Records of drilling predation on scaphopod mollusc are rare. Here, we report naticid drilling predation on scaphopods from a “Turritelline-dominated assemblage” (TDA) stratigraphically just below the K-Pg boundary sections in Rajahmundry, India, which was situated in the Southern Hemisphere during that time. Low drilling frequency was found in the present assemblage based...

Abstract One of the important and well documented prey–predator interactions in the fossil record is drilling predation done by naticid gastropods which diversified during the Cretaceous. Although drilling frequencies showed fluctuating patterns, most of the previous studies argued that naticid drilling predation was less intense during the Cretaceous and the modern values were achieved since the Paleocene. We, here, present a new dataset of naticid drilling predations, involving 31,929 gastropo...

Evidence of intense naticid drilling predation occurs on turritelline prey from a turritelline-dominated assemblage (TDA) which lies below the K-T boundary sections in Rajahmundry, India. Previously, it was believed that drilling frequency (DF) on turritelline taxa was low during the Cretaceous. Data from the study area indicates that the Cenozoic level of predation on turritelline taxa already occurred by the Late Cretaceous in the study area. The paleobiogeography of naticid predation is exten...

Predator-prey interaction is an important aspect of biological system. Gastropod drilling predation can be traced in the fossil record and provide many reliable information about drilling activities e.g., drilling intensity, efficiency of predators through size and site stereotypy. Drilling frequency (DF) varies widely in space and time. Temporal changes, although complex, depicts a pattern. Drilling frequency was low during the Cretaceous and cyclically increased during the Eocene and Miocene. ...

Abstract Perisphinctes Waagen, 1869 is an important genus of the Oxfordian. In many areas the taxon has been excessively and subjectively split. Based on the material collected in Kutch (India), including the type specimens, we have grouped eight species previously described as distinct into one biological species, Perisphinctes indogermanus Waagen, 1875 . It is characterized by strong sexual dimorphism. Macroconch shows high intraspecific variability. Microconch is previously described from Kut...

Abstract The study of past biotic interactions is important not only to understand the paleoecological history of a community, but also to test the evolutionary role of such interactions. Drill holes in invertebrate exoskeletons provide one of the very few scenarios where biotic interaction could be studied directly and the related hypotheses could be tested with statistical rigor. Hence, the documentation and interpretation of the spatio-temporal patterns of drill hole frequencies has been the ...

Abstract The genus Choffatia (Siemiradzki) is an important Callovian ammonite in Kutch biostratigraphy. Several species of the genus were described by the early workers who did not recognize intraspecific variability and sexual dimorphism in terms of the modern concepts. We have described here three dimorphic species based on material reposited in the Geological Survey of India, Kolkata as well as systematically collected additional specimens with precise stratigraphic information. These species...
