Calvin and Hobbes creator Bill Watterson is the kind of cartoonist who makes everything look insanely cool, particularly when he contrasts raw cartooning with a little rendered-just-right realism. That's why today, International Dinosaur Day, is the perfect time to reflect on Watterson's expertly-etched triceratops, pteranodon, brontosaurus, allosaurus, ultrasaurus, diplodocus, stegosaurus, quetzalcoatlus, predacious, deinonychus, chasmosaurus, and... Calvinosaurus!

We selected 30 of the most Mezozoic Calvin and Hobbes strips to help you start your Dino Day off right. Dig in, below:
