The centimeter wide rock layer that records the Cretaceous–Paleogene boundary that ended the rein of the dinosaurs. (It's the brown layer between the coal & light claystone layers.) It was created by the fallout of a 12km impactor that created the 250km wide Chicxulub crater offshore of the Yucatán Peninsula. The layer contains shocked quartz & an anomalous concentration of the element iridium marking an extraterrestrial impact.

"Deep Time Australia
is an ABC News Story Lab project that provides a glimpse into the ancient history of Aboriginal and Torres Strait Islander people who have occupied this land for more than 65,000 years. The stories contained in this project belong to the knowledge holders and keepers, and they have been generously shared with the ABC for this project. Without them the beautiful complexity of this project would not have been possible."Tell me a story:

To the world, the Oak is merely fodder for the hearth or an obstacle to "renewal."
But the Oak is a survivor. While we overheat in discourse, it cools the air. It heals by connecting, refusing to be bent by the crimes committed against it.
Stop with the wisdom of the Gretas. Put aside your sociology degrees.
The Oak is the true manifesto for a complex society—Read on: https://library.profpeter.my/paper-trails/mastodon-short/true-science-of-the-oak

"Frankly, I’m surprised you’re even interviewing me. Geologists generally treat me as a nonentity. I’m an un-rock, a cipher, just an irregular surface."

🧬 Life kept upgrading itself, code rewriting code. Single cells learned to cluster, then specialize, then network. Fungi arrived early, aquatic, flagellated, flinging spores like packets through water. They hacked land via algae, spun mycelial grids under shifting continents, laid dark infrastructure for everything that followed.
Evolution doesn’t rush toward dominance. It stabilizes conditions until dominance becomes possible.

"this problem of deep time still haunts us, because it lurks behind the challenge of grasping #climatechange — i.e. the fact that the warming we’re currently seeing is happening far faster than it ought to. You can only really grasp the speed of what’s going on if you grasp the depth of time …"

#ICYMI “rocks are best understood not as nouns but verbs, signifying events and processes…Herein lies Earth’s secret to wrinkling time…Accepting that we too live in geologic time can free us from narcissism…We may then realize that the text of the Earth itself is full of guidance on durable design and start laying the groundwork for a post-Anthropocene world” https://emergencemagazine.org/essay/wrinkled-time/ via @emergencemagazine re: #deeptime #geologictime + more

DeepTime: Explore an epic story 65,000 years in the making
The ABC has recently released Deep Time, “an interactive tool the Story Lab team within ABC News created to help all Australians better understand the ancient history of our continent and its First Nations peoples.”

#Sanidine from the Fish Canyon Tuff is essential to understanding the pace of events in the #Cenozoic
High potassium, quickly erupted and cooled, and old enough to have accumulated sufficient 40Ar from radioactive decay. These crystals calibrate neutron flux for 40Ar/39Ar dating. The 28.2 Ma age of the FCT sanidine has been fine-tuned using #Milankovitch cycles of other ash beds in stable sedimentary basins.

"With your arms spread wide again to represent all time on earth, look at one hand with its line of life. The Cambrian begins in the wrist, and the Permian Extinction is at the outer end of the palm. All of the Cenozoic is in a fingerprint, and in a single stroke with a medium-grained nail file you could eradicate human history."
-- John McPhee, _Basin and Range_, pg 126

'It is a journey into an entirely new way of seeing and thinking about the legacies that we're leaving, the way that we inhabit this planet' - Rob Petit talks to us about documentary Underland https://www.eyeforfilm.co.uk/feature/2025-06-18-rob-petit-on-taking-a-dive-into-deep-time-inheritance-and-legacy-in-documentary-underland-feature-story-by-amber-wilkinson #tribeca2025 #documentary #DeepTime

what but imagination could have read
granite boulders back to their molten roots?
And how far back was back, and how far on
would basalt still be basalt, iron iron?—Edwin Morgan certainly though so, and was inspired – by Burns & Hutton – to write “Theory of the Earth” (first published in New Writing Scotland 2, 1984)

Till a’ the seas gang dry, my dear,
And the rocks melt wi’ the sun…James Hutton met Robert Burns in 1787. Later that year, Burns chose to visit some of the sites discussed in Hutton’s THEORY OF THE EARTH. Is there an echo of Hutton’s “deep time”—oceans evaporating, rocks melting—to be heard in Burns’s “A Red, Red Rose” (pub. 1794)?

James Hutton (1726–1797), father of modern geology, was born #OTD, 14 June (NS; 3 June OS). One of the first European proponents of “deep time”, the conclusion of his 1788 paper “Theory of the Earth” has been called one of the most lyrical sentences in all of science:
The result, therefore, of our present enquiry is, that we find no vestige of a beginning,—no prospect of an end.

Let's go further back into #deeptime.
Archaeological evidence from South Africa (160,000-200,000 years ago) shows #humans engaged in creating art, new tools, and beads.
How did those humans do #politics 140,000 years ago?
Who the hell knows. But they did, necessarily.
And that is something fascinating to keep in mind for later.

🧵 #OTD the #Titanic sank in 1912. When I was a very small child, I knew an old woman who narrowly escaped this disaster. As the governess of a US millionaire's children, she was supposed to be travelling on the Titanic. They arrived too late in England and couldn't get tickets.
Shortly before her death, she gave me some old #yarn. I haven't dared to use it to this day because it's like travelling back in #deepTime. 113 years can feel so near.
