Trove of Dinosaur Feathers Found in Canadian Amber
An extraordinary collection of ancient feather fragments preserved in amber has opened a window into a lost world, one that now appears populated by dinosaurs covered in plumage as rich and varied as that of modern birds. [More]
“This image was taken in winter time in a arid area of the Canadian Rockies. Temperatures where below -30 degrees Celsius yet because there was no snow fall the surface of the lake was uncovered allowing me to see and capture the bubbles (gas release from lake bed) that were trapped in the frozen waters.”

Canada—Fluttering wings leave lacy trails as moths beat their way to a floodlight on a rural Ontario lawn. The midsummer night’s exposure, held for 20 seconds, captured some of the hundreds of insects engaged in a nocturnal swarm. Photo by Steve Irvine

At the coast at Mistaken Point in Canada, there are large slabs of rock and on them imprinted intricate shapes. These are pre-Cambrian fossils of animals (not plants), before animals had eyes and moved around lots. Their intricate shapes are fractal-like, similar to ferns; they seem to be constructed by a branching process where big sections branch off into smaller sections which branch off into even smaller sections etc… Thus there is similarity on many scales, similar to the mathematical notion of a fractal (similar on all scales). These were some of the first multi-cellular animals, before the bi-symmetric body-plans of animals like ourselves. Fractal like branching rules are simple to code for genetically, but produce complex intricate shapes like this. [more (pdf)] [my colouring in! these things were likely to be colourless]
