Paleoecology of naticid-molluscan prey interaction during the Late Jurassic (Oxfordian) in Kutch, India: Evolutionary implications

Subhendu Bardhan, Sandip Saha, Shiladri Das & Ranita Saha
We document and quantify one of the oldest predator-prey interactions between naticid gastropods and molluscan prey, based on drill holes in shells, from the Late Jurassic (Oxfordian) beds of Kutch, western India. Previously, many workers recorded naticid-like drill holes on prey taxa from the Triassic and the Jurassic, but in the absence of associated naticid body fossils, they remained equivocal. The present gastropod community is dominated by turritellines (98% of the sample) which form the...

Scheduling Mechanisms to Control Spread of Covid-19 (Simulation Results)

Khalid Hourani, John Augustine, Anisur Molla, Gopal Pandurangan & Adi Pasic
We study scheduling mechanisms that explore the trade-off between containing the spread of COVID-19 and performing in-person activity in organizations. Our mechanisms, referred to as group scheduling, are based on partitioning the population randomly into groups and scheduling each group on appropriate days with possible gaps (when no one is working and all are quarantined). Each group interacts with no other group and, importantly, any person who is symptomatic in a group is quarantined. We...

A new faunistic component of the Lower Triassic Panchet Formation of India increases the continental non-archosauromorph neodiapsid record in the aftermath of the end-Permian mass extinction

Martin Ezcurra, Saswati Bandyopadhyay & Kasturi Sen
The fossil record of Early Triassic diapsids is very important to understand how the end-Permian mass extinction affected ecosystems and the patterns and processes involved in the subsequent biotic recovery. Vertebrate fossil assemblages of continental deposits in current-day South Africa, China and Russia are the best source of information of this clade during the aftermath of the extinction event. Although considerably less sampled, the Induan continental rocks of the Panchet Formation of the Damodar Basin...
