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."

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 …"
