Earthworm Bounty Calculated

Earthworm bounty calculated by scientists who correlated a global atlas of earthworm abundance with maps of agricultural production, taking into account soil properties and artificial fertilisers. They concluded: “Our findings indicate that earthworms contribute to roughly 6.5% of global grain (maize, rice, wheat, barley) production and 2.3% of legume production, equivalent to over 140 million […]

Octopuses’ Guide to Punching Fish

Yes, octopuses have been observed to punch fish with great accuracy, so a group of scientists have studied the biomechanics of how they do this.  They found a well-coordinated set of movements involving sending abend down the arms closest to the fish, then rotating the arms outwards while using the other arms to grip rocks […]

Ammonite fossil embedded in rock

Archaeopteryx and Ammonite

In 2018 scientists from Germany and Switzerland published a detailed description of an Archaeopteryx specimen they claimed to be the oldest Archaeopteryx.  One reasons they claim this record is that the specimen was buried alongside an ammonite – an extinct spiral-shelled sea creature similar to a nautilus. Reference: Rauhut et al. (2018), The oldest Archaeopteryx […]

A Treasure Trove of Welsh Fossils

Palaeontologists in Wales have found a deposit very well preserved fossils described as “a highly diverse Middle Ordovician Burgess Shale-type fauna”. The fossil deposit is dated as 462 million years, over 20 million years after the Cambrian period in the evolutionary timetable.  The fossils include some well-known Cambrian creatures that are now extinct, as well […]

Oldest Fossil Brain

An international team of scientists have studied the fossil of a lobopodian, a small extinct arthropod with a segmented trunk and multiple short stubby legs.  The fossil has been named Cardiodictyon catenulum and is dated as 525 million years old.  Using sophisticated scanning techniques the researchers were able to identify the creature’s brain.  Nicholas Strausfeld […]

Barrier Reef ‘Re-Cover Up’

A survey of the Great Barrier Reef by the Australian Institute of Marine Science (AIMS) has found the northern and central reef regions have the highest coral cover seen since the regular surveys began 36 years ago. The Great Barrier reef is not one single reef but a large series of reefs along the coast […]

Red Algae

Pollination in the Sea

A group of European researchers have studied a seaweed named Gracilaria gracilis that grows in the tidepools around Europe.  This seaweed is in a class of red algae known as Florideophyceae, and has separate male and female forms.  Unlike many marine organisms the females do not release their eggs into the water to be fertilised, […]

Trilobites

Trilobite Eyes Inspire Bifocal Lenses

Researchers from China and the USA have studied the eyes of a trilobite named Dalmanitina socialis.  These creatures had ‘bifocal’ eyes consisting of two lenses that bent light at different angles, enabling them to see both close up and far away objects at the same time. The researchers were “inspired by the optical structure of […]

Mushrooms on Forest Floor

Slugs Ferry Fungal Spores.

Fungi are important for breaking down leaf litter and wood debris in forests, and some form symbiotic relationships with trees and shrubs, which helps nourish both the trees and the fungi.  Mushrooms and other visible fungi are the fruiting bodies, or reproductive structures, of fungi that live in the ground.  They release spores into the […]

10-Armed Octopus Ancestor?

Palaeontologists at the American Museum of Natural History (AMNH) and Yale University have studied the fossil of soft-bodied creature with 10 arms and claim to have found the oldest known vampyropod – the group of animals that includes octopuses and vampire squids. The fossil was found in the Bear Gulch Lagerstätte of Montana, USA, a […]
