¡Corre a por ella!
Running the FRANTZ to magnetically separate the garnet from my sample, all the stuff falling out is the less magnetic amphibole. For anyone curious I’m dating the Syros monolith
Fun fact: the guys at our college’s geology department prop out the doors with their samples. I totally understand why but as someone whose work with samples is necessarily super delicate and sterile it fucks me up so bad
What did South Eastern Australia look like 130 million years ago? This watercolour landscape is part of my on going work recontructing fossils discovered last summer in Boola Boola Forest, Gippsland Victoria. They date back to the Early Cretaceous period - the golden age of the dinosaurs.
.
On our dig we found fossils of every species shown in this illustration. The plants in the foreground and fossil shown here is Otozamites douglasii, a member of the cycad-like Bennettitales which are completely extinct now. However the rest of the scene depicts plants that have similar modern decendants: Cladophlebis ferns down low, a forest of conifers including Bellarinea richardsii (Podocarp family), and very tall Brachphyllum tyersensis (Belonging to either the Araucaria or Cypress family).
This fossil is not of an animal, but a mineral. When sea water temperature at the seafloor drops below ~4°C/39°F a carbonate mineral called ikaite will start to precipitate and grow forming bizarre shapes. Even though the original mineral will dissolve once it is buried, other diagenetic minerals will replace its form, making a glendonite.
Gledonite/Ikaite and its specific forming conditions allow geologist to approximate climatic conditions for the time period captured by the rocks in which this mineral is found.
Thanks to the flat exposure on the rock platform, we can appreciate this nature’s creativity.
