A localized geochemical and biological model explaining anomalous carbon-isotope signatures found in 2-billion-year-old Karelian rocks, challenging the prevailing theory that these signatures indicate a global carbon-cycle disruption.

The rate-mismatch hypothesis posits that global mass extinctions occur when the pace of environmental change outstrips the rate at which biological life can undergo evolutionary adaptation. It provides a mathematical model linking Earth's historic extinction events to the critical disparities between environmental shifts and species' adaptive capabilities.

The evolutionary advantage of photosymbiosis in corals is not a fixed biological trait but is contingent upon environmental context, as demonstrated by a 500-million-year analysis of coral survival.

Prototaxites
"About 400 million years ago—long before the first giant dinosaurs—a massive and strange organism up to 8 meters long loomed over the Lilliputian plants, mushrooms, and bugs that carpeted the land"
Not a fungus. Not a lichen. Not a plant ...
An unknown branch of multicellular life that went extinct

Stage (stratigraphy) (Geology terminology ⛰️)
In chronostratigraphy, a stage is a succession of rock strata laid down in a single age on the geologic timescale, which usually represents millions of years of deposition. A given stage of rock and the corresponding age of time will by convention have the same name, and the same boundaries. Rock series are divided...

Chronozone (Geology terminology ⛰️)
A chronozone or chron is a unit in chronostratigraphy, defined by events such as geomagnetic reversals, or based on the presence of specific fossils. According to the International Commission on Stratigraphy, the term "chronozone" refers to the rocks formed during a particular time period, while "chron" refers to that time period. ...

Do you want to know how the structure of the rock record affects your reconstructions of #biodiversity, #evolution rates or trait evolution? The groundwork for doing this has been laid down in the field of #StratigraphicPaleobiology but until now no software tools have been available to researchers in #paleobiology and #geoscience to evaluate distortion of their #FossilRecord.
Join the webinar on Building modeling pipelines for stratigraphic paleobiology in #RSoftware by my PhD student @Niklas_Hohmann in the Paleoverse lecture series hhttps://palaeoverse.org/lectures this Thursday at 4 PM UTC to learn how to use the new package StratPal developed in my European Research Council (ERC) project #MindTheGap
You can find the package with extensive documentation here: https://mindthegap-erc.github.io/StratPal/

If you are interested in working with us on #StratigraphicPaleobiology, structure of the fossil record, and development of #OpenSource research software, please get in touch!
🔴 🇳🇴 Corroborating written history with ancient DNA: The case of the Well-man described in an Old Norse saga
"Here we apply palaeogenomic analysis to human remains excavated from a medieval well at the ruins of Sverresborg Castle in central Norway. In Sverris Saga, the Old Norse saga of King Sverre Sigurdsson, one passage details a 1197-CE raid on the castle and mentions a dead man thrown into the well. Radiocarbon dating supports that these are that individual’s remains."

A sorta exclusive for #TetZooCon 2024... we have Dave the Hone talking about his brand-new book DINOSAUR BEHAVIOUR, and - hopefully - we'll have copies present at the meeting ahead of the actual publication date. Woohoo! It features art by @serpenillus (who, sadly, isn't able to attend....) #dinosaurs #palaeobiology #paleobiology

“Organ systems of a Cambrian euarthropod larva”, Smith et al. 2024
https://www.nature.com/articles/s41586-024-07756-8
“we describe the internal and external anatomy of a three-dimensionally preserved euarthropod larva with lobopods, midgut glands and a sophisticated head. The architecture of the nervous system informs the early configuration of the euarthropod brain and its associated appendages and sensory organs, clarifying homologies across Panarthropoda.”
