Dinosaurs, Chalk Cliffs, and Me: My Life As a Garden

Dinosaurs, Chalk Cliffs, and Me: My Life As a Garden

My raised bed at Hogge Park measures six feet by 18. Bigger than a coffin. Not by much. A metal fence runs along one side of it — put up, in roughly equal measure, to keep out deer and non-gardeners. Close enough to touch if the fence weren’t there is a Greek Orthodox church, its dome catching the morning light while I stand at the bed pulling the rare weed that manages to take hold. They do resurrection over there — incense, icons, a body that doesn’t stay dead. I do mine over here, with a trowel and a bag of composted leaves, and mine takes all season and ends every fall in a heap of black rotted matter that doesn’t look like resurrection at all. It looks like the floor of a well-shaded forest — dark, loamy, unremarkable — the kind of ground you’d walk across without a second thought, never guessing what it’s about to become. Hogge Park sits in suburban Washington, barely a mile from the spot where Abraham Lincoln once rode …

The full story of the dinosaurs, from extinction to extinction

The full story of the dinosaurs, from extinction to extinction

Steve Brusatte, the paleontologist behind Jurassic World’s science and author of The Rise and Fall of the Dinosaurs and The Story of Birds, walks through what fossils actually prove versus what Hollywood invented.  Brusatte traces dinosaurs back to footprints smaller than a house cat, found in Poland just after the worst mass extinction in Earth’s history, and explains why those early survivors spent millions of years as background characters next to car-sized salamanders and armored crocodiles. This video The full story of the dinosaurs, from extinction to extinction is featured on Big Think. Source link

Identifying dinosaurs from their footprints is difficult – but AI can help

Identifying dinosaurs from their footprints is difficult – but AI can help

When you hear the word “dinosaur”, the first thing that might spring to mind is a hulking skeleton like Sue the T rex in Chicago’s Field Museum or Sophie the Stegosaurus at the Natural History Museum in London. Dinosaur skeletons give us striking evidence of what these ancient animals looked like, from the plates and spikes on stegosaurs like Sophie to the long-necked, airplane-sized bodies of titanosaurs. However, despite their iconic status as museum centerpieces, skeletons are not the most common type of dinosaur fossil known. That prize goes to dinosaur footprints. The abundance of dinosaur footprints is intuitive. Each dinosaur could only leave one skeleton – but on any single day of its life, it could make thousands of footprints. So, even if only a tiny fraction were fossilised, we could expect to see many more of them in the fossil record. Dinosaur footprints form in environments where the ground is soft enough to leave an impression, but still cohesive enough so that the shape of the track does not collapse. We find dinosaur …
