High resolution techniques reveal clues in 3.5 billion-year-old biomass

Science Daily - Fossils - Wed, 02/21/2024 - 20:38
To learn about the first organisms on our planet, researchers have to analyze the rocks of the early Earth. These can only be found in a few places on the surface of the Earth. The Pilbara Craton in Western Australia is one of these rare sites: there are rocks there that are around 3.5 billion years old containing traces of the microorganisms that lived at that time. A research team has now found new clues about the formation and composition of this ancient biomass, providing insights into the earliest ecosystems on Earth.

Painting a tree's pruning wounds may be useful after all

New Scientist - Wed, 02/21/2024 - 12:00
Since the 1970s, gardening wisdom has written off as useless the old practice of painting a tree’s pruning wounds. James Wong isn’t so sure

Humpback whales have a specialised larynx for underwater singing

New Scientist - Wed, 02/21/2024 - 10:00
The distinctive melodies of baleen whales are produced by pushing air against a fatty cushion on one side of the larynx, and a sac lets them recycle air back into the lungs

Panama Canal expansion rewrites history of world's most ecologically diverse bats

Science Daily - Paleontology - Tue, 02/20/2024 - 13:44
In a new study, paleontologists describe the oldest-known leaf-nosed bat fossils, which were found along the banks of the Panama Canal. They're also the oldest bat fossils from Central America, preserved 20-million years ago when Panama and the rest of North America were separated from southern landmass by a seaway at least 120 miles wide.

Deadly plant kills its pollinators but nurses their young

New Scientist - Tue, 02/20/2024 - 09:00
A deadly flower kills the gnats that pollinate it but may help the insects’ offspring in return, which indicates that plant-pollinator relationships may be more complex than previously thought

Why two prehistoric sharks found in Ohio got new names

Science Daily - Paleontology - Mon, 02/19/2024 - 12:07
Until recently, Orthacanthus gracilis could have been considered the 'John Smith' of prehistoric shark names, given how common it was. Three different species of sharks from the late Paleozoic Era -- about 310 million years ago -- were mistakenly given that same name, causing lots of grief to paleontologists who studied and wrote about the sharks through the years and had trouble keeping them apart. But now a professor has finished the arduous task of renaming two of the three sharks -- and in the process rediscovered a wealth of fossil fishes that had been stored at a museum for years but had been largely forgotten.

Mystery solved: The oldest fossil reptile from the alps is an historical forgery

Science Daily - Paleontology - Fri, 02/16/2024 - 12:58
Palaeontological analysis shows that a renowned fossil thought to show soft tissue preservation is in fact just paint. The fossil discovered in 1931 was thought to be an important specimen for understanding early reptile evolution. While not all of the celebrated fossil is a forgery, scientists urge caution in how the fossil is utilized in future.

Searching for clues in the history book of the ocean

Science Daily - Paleontology - Thu, 02/15/2024 - 15:06
New research has shown that the tropical subsurface ocean gained oxygen during the Paleocene-Eocene Thermal Maximum (commonly referred to as PETM). During this short-lived interval of time in Earth s history that occurred 56 million years ago the average temperatures rose by up to six degrees within a few thousand years.

A lighthouse in the Gobi desert

Science Daily - Paleontology - Wed, 02/14/2024 - 19:33
A new study explores the weight great fossil sites have on our understanding of evolutionary relationships between fossil groups and quantified the power these sites have on our understanding of evolutionary history. Surprisingly, the authors discovered that the wind-swept sand deposits of the Late Cretaceous Gobi Desert's extraordinarily diverse and well-preserved fossil lizard record shapes our understanding of their evolutionary history more than any other site on the planet.
