The invertebrate trace fossils Selenichnites rossendalensis and Crescentichnus tesiltus are recorded and described from the Middle Jurassic Gristhorpe Member of the Cloughton Formation of the Cleveland Basin. This is the first record of these ichnospecies from the basin and now completes the occurrence of these and other traces assumed to have been made by limulids from all three non-marine formations of the Ravenscar Group.

Calcareous nannofossils are a group of micrometric fossils abundantly found in marine sediments. This group is mainly composed of coccoliths, platelets produced by the unicellular algae coccolithophores, and nannoliths whose biological affinity remains unknown. Calcareous nannofossils have a continuous record for the past 215 myr (Bown 1998) and can be found in almost every marine environment from coast to open oceans and from the Equator to the poles in surface waters (Winter et al. 1994). These microfossils are also made of low-Mg calcite (Siesser 1977; Stoll et al. 2001) which is resistant to dissolution and a common matrix for geochemical analyses in palaeoceanography. Hence, calcareous nannofossils could be one of the best fossils for palaeoceanographical studies for the last 215 myr. Their use in geochemistry is, however, less common than planktic foraminifera due to their small sizes, masses (10–1000 pg) and complex vital effects. Despite the fact that nannofossils are very small (2–20 µm), the development of high-resolution analytical devices opens up the opportunity to analyse single nannofossils or even parts of them. This is a growing field of nannofossil research.

Learning more about flying reptiles that lived more than 200 million years ago could help more efficient drones be developed, scientists have said.

Strawless in Seattle is now officially enshrined into law.

The newfound fossils shed light on the early evolution of one of the planet’s most mysterious amphibians.

Beeps!

A senior citizen was brutally murdered in Koparkhairne on Monday afternoon. The police said some unknown people barged into his flat and beat him to death with the utensils in the house. He was found lying on the floor, covered in blood when the Koparkhairane police reached the spot. The police are interrogating his son who was at home at the time of the incident.

The victim, identified as Vijaykumar Darote, 62, had been living with his only son in a Koparkhairne high-rise for the past few years. On Monday afternoon, some unknown people came to Darote's house on the fifth floor of the building and when he opened the door, they pushed their way in and started beating him up with rods and utensils. When his son tried to intervene, they beat him up, too, and fled from the house.

ACP Pradeep Jadhav said, "We got a call from Darote's son who was present at the time of the brutal assault. He, too, is injured and has been admitted to a hospital. Darote had too many injuries because of which, he died by the time we brought him to the hospital. We are checking CCTV footage of the area and trying to find out the reason behind the murder. We have already started a search for the accused and will arrest them soon."

This week we have stories on what body cams reveal about interactions between black drivers and U.S. police officers, the world’s oldest Homo sapiens fossils, and how modern astronomers measured the mass of a star—thanks to an old tip from Einstein—with Online News Intern Ryan Cross. Sarah Crespi talks to Eyal Ben-David about a pair of selfish genes—one toxin and one antidote—that have been masquerading as essential developmental genes in a nematode worm. She asks how many more so-called “essential genes” are really just self-perpetuating freeloaders? Science Careers Editor Rachel Bernstein is also here to talk about stress and work-life balance for researchers and science students. Listen to previous podcasts.
