Dinosaurs lived in greenhouse climate with hot summers, study shows

Posted: 10 Jun 2021 10:56 AM PDT

Researchers have developed an innovative way to use the clumped isotope method to reconstruct climate in the geological past on the seasonal scale. They show that dinosaurs had to deal with hotter summers than previously thought. The results suggest that in the mid latitudes, seasonal temperatures will likely rise along with climate warming, while seasonal difference is maintained. This results in very high summer temperatures.

The rocky road to accurate sea-level predictions

Posted: 10 Jun 2021 10:56 AM PDT

The type of material present under glaciers has a big impact on how fast they slide towards the ocean. Scientists face a challenging task to acquire data of this under-ice landscape. Choosing the wrong equations for the under-ice landscape can have the same effect on the predicted contribution to sea-level rise as a warming of several degrees, according to researchers.

Researchers link ancient wooden structure to water ritual

A team used dendrochronology and a form of radiocarbon dating called 'wiggle-matching' to pinpoint, with 95% probability, the years in which an ancient wooden structure's two main components were created: a lower tank in 1444 B.C., and an upper tank in 1432 B.C.

Ceramics provide insights into medieval Islamic cuisine

A group of ancient amphibians called temnospondyls evolved stiffer spinal columns to adapt to aquatic life, contrary to previous hypotheses, according to a new study.

The iron jaws of the bristle worm

Bristle worms have remarkably stable jaws. They are made of a very unusual material containing protein structures and metal atoms. Scientists have now been able to analyze and explain the properties of these structures, which could lead to novel industrially usable materials.

Maori connections to Antarctica may go as far back as 7th century, new study shows

Indigenous Maori people may have set eyes on Antarctic waters and perhaps the continent as early as the 7th century, new research shows.

Diverse fossil flora from 400 million year ago

The analysis of very old plant fossils discovered in South Africa and dating from the Lower Devonian period documents the transition from barren continents to the green planet we know today.

Archaeology uncovering lost Indigenous NE Florida settlement of Sarabay

Posted: 08 Jun 2021 12:44 PM PDT

Archaeology team is now fairly confident they have located the lost Indigenous northeast Florida community of Sarabay, a settlement mentioned in both French and Spanish documents dating to the 1560s but had not been discovered until now.

10,000-year-old DNA pens the first tales of the earliest domesticated goats

Posted: 07 Jun 2021 01:11 PM PDT

New research has revealed the genetic makeup of the earliest goat herds. The findings, assimilated from DNA taken from the remains of 32 goats that died some 10,000 years ago in the Zagros mountains, provide clues to how early agricultural practices shaped the evolution of these animals.

Experiment evaluates the effect of human decisions on climate reconstructions

Posted: 07 Jun 2021 05:46 AM PDT

The first double-blind experiment analysing the role of human decision-making in climate reconstructions has found that it can lead to substantially different results.
