Fascinating study decoding the evolution of sensory capacities directly from trace fossils
"exponential expansion of sensory distance from millimetric contact-based sensing subcentimetric chemo-/mechanosensation to decimetric long-range visual-sensation by the terminal Ediacaran"

"The approach includes separate models for process and observation error, and simultaneously estimates coefficients of environment-species relationships and species-species interactions."

I thought that 476 is not a great number, but it is just a sample, if we take that the necropolis is 20 km X 1200 km long (estimate from presented map) and active carcass density 7.81 whale falls per square kilometre we should have ≈ 190,000 whales.

Retarding effects of the domestication. Compare the skulls of the 'Chad" auroch (Bos primigenius) on the right, and it's descendant - domestic cattle (Bos taurus) on the left. Photo taken in the Zoology museum of the Jagellonian University.

Continental weathering—a driver of one of the profound biogeochemical excursions:
"Shuram Excursion was characterized by intense congruent continental weathering that delivered river water to the global ocean with extremely low δ7Li composition"

Cool study about the nature of Holocene cold events. Spoilers—the culprit is the rare super-collosal eruption and volcanic winters:
"Over 80% of Holocene glacial advances occurred within chronological uncertainty of at least one large (M≥7) eruption in the northern hemisphere."

A very interesting study on the growth of complexity by subtraction!
"Bones lost in lissamphibians exhibited greater morphological disparity and evolutionary rates in temnospondyls than retained bones. This indicates that developmental bias"

Good taxonomy is a key to all of the paleobiology (along with stratigraphy and taphonomy). A new giant mosasaur is described - the T. rex (Tylosaurus rex), which extends the size spectrum of vertebrate predators and thus enables the re-interpreation of functional ecology in the Late Cretaceous seas 👇
