I was once walking around Crystal Palace Park, waiting for a movie festival to begin, when a man approached me and my friend and asked us if we had seen the dinosaurs. We were confused at first, but he quickly pointed at some massive and frankly strange-looking sculptures that were spread around the park. Only ...

Ammonites are amongst the most popular fossil, and they have every right to do so. These beautiful spiral creatures are somewhat related to octupuses and squids, the only difference being that they went extinct 75 million years ago, along with the dinosaurs. When ammonites originated, they were planktonic and tiny. Less than 1mm tiny. As they ...

Here at the visual squirrels, we are not in the habit of promoting stuff, but Calamityware is simply too funny. Taking the classic language of cobalt and porcelain decoration, the artist Don Moyer adds – well – calamity. Volcanoes, robots, tentacles, and all manner of funny creatures hide in the china. The only problem with ...

I made this infographic to show the (current state of things for) human evolution. Or quite current, because there have been some new discoveries, but they are still being debated. Feel free to download, distribute and change it, but please don't crop my name off it as it took me a long time to make it! Licence ...

A long time ago I made a geologic timeline as a (vector) brush in Illustrator, with .ai and .eps files free for anyone to use. The only thing I ask is that if you use it, let me see the result. Making the timeline was incredibly time-consuming and ludicrously fiddly. So, a while ago I got ...

Yisela The Upper Paleolithic or Late Stone Age begins and ends with a revolution. The first one is what can be considered the 'official' appearance of art, some 50,000 years ago. The second, the invention of agriculture, 40,000 years later. The earliest sample of Paleolithic art is the shells with holes and chipped edge modifications from Ksar Akil. These flakes show regular teeth distributed ...

Jack Horner is a paleo-dude of the purest water. He is funny, knowledgeable and loves dinosaurs so much he wants to build one. And it is actually feasible. Chickens are basically altered dinosaurs, and fiddling with switching on and off genes will give you a chickenosaurus. See the TED talk. Best dude around ...

During an extended period of the depression in USA (between 1935-1942), the US federal government supported artists by commissioning artwork for non-federal places and activities. Early on in the project, posters were painted by hand, each individually created. Later on, they were printed with silk screen. According to the US library of congress, "over two ...

pterodactyl Archaeopteryx Hoatzin bird I am going to skip over the arguments against the imbeciles who believe that the world is 6000 years old. Richard Dawkins are nobly taking that task upon himself. About 150 million years ago, the pterodactyl roamed the skies (pterodaktulos, meaning "winged finger"). There is something about that shape (and size!) ...

Drawing is a skill, art is a gift. I am no artist, but I draw, and the same rule for learning to play the piano applies: practice, practice, practice. I have briefly mentioned earlier my deep belief in doodles. I will in a later post come back to my technique and how I go about ...
