The #Phanerozoic Eon constitutes the current and most biologically dynamic division of the geological time scale. Spanning the interval from approximately 538.8 million years ago (Ma) to the present day, it represents roughly the last 12% of Earth's 4.54-billion-year history

#WeekendReading: Canfield et al., looking at some proxy records for continental weathering to see how it changed between the #Proterozoic and #Phanerozoic, and how it might have affected the #sea.

#WeekendReading: Faulkner et al. on how the test walls of foraminifera change through the #Phanerozoic and what might have to do with #ocean chemistry.

I have my own critique on the possible over-focus on #reefs sometimes, but the simple fact is, today and across the #Phanerozoic, reefs have been loci of #biodiversity hotspots.

An important — but also surprising — study reports new climate estimates over the last 500 million years.
It estimates Earth's mean temperature has swung between ~10 °C and ~35 °C (~50 °F and ~95 °F), a much larger range than previously believed.

Revolution an der Tanzbar: The #Ocean - #Phanerozoic II (Live for Roadburn Redux)
"We wanted to give people 2 totally different experiences with these 2 shows. Phanerozoic I was streamed live from a venue in the port of #Bremen, with big lighting production, kind of the way people know us. For Phanerozoic II, we wanted to do something more cinematic visually, and at the same time more intimate. We wanted to capture the feeling of the 6 of us in a relatively small, confined space, facing each other, in a circle... without a stage or a crowd being any part of this equation. It was March and the room that we spent the whole day in was cold, but that was part of the vibe. We had to warm up our fingers constantly.” comments the band.

A persistent influence of #supernovae on #biodiversity over the #Phanerozoic: https://onlinelibrary.wiley.com/doi/10.1002/ece3.9898 -> the number of exploding stars (supernovae) has significantly influenced marine life's biodiversity during the last 500 million years: https://www.eurekalert.org/news-releases/983477

A large body of evidence has focused on abrupt #climate change as a direct or indirect mechanism that drove many mass and minor extinctions.
The significant relationship between temperature change and #extinction still exists when we exclude the five largest mass extinctions of the #Phanerozoic.
Temperature increase of 5.2 °C above the pre-industrial level would likely result in mass extinction, even without other, non-climatic #anthropogenic impacts.

What exactly happened during these vast stretches of #geologic time, though? That's the question that #AbbyHoward seeks to answer in her #EarthBeforeUs #comic series. The three #graphicnovels take readers through the three #eras of the #Phanerozoic #Eon, though slightly out of order. #DinosaurEmpire is a better hook for a first book, after all! #OceanRenegades & #MammalTakeover are just as fascinating, though, so be sure to read them all!
These are a #DinoDadReviews fav.

@PaleoParaDive #Postdoc Aleksandra Skawina has wide expertise on the #evolution of freshwater #bivalves, #taphonomy and #paleoecology as well as with conducting #ecophysiological #experiments on living bivalve species and #teaching. She leads our efforts to create a #Phanerozoic #database of associations and #paleopathologies linked to #parasitism and co-leads the #Paleosynthesis #BITE workshop. She makes beautiful #scientific hand #drawings #paleoart. She is #mom of one, and has a cat on board
