    Here’s a collection of online bric-a-brac with connections to this site’s gaming material: Dinosaurs and their tails Having written about both dinosaur design and tail design, I can’t help but comment on the Smithsonian blog’s report that dinosaurs may have had thicker, beefier tails than often depicted. Sounds fine to me, at least until we get that cloning process working to verify things. What does that mean for critter design? Well, nothing, really. About all I can note is that, using the above tail rules, your dinos really should go for the heavy tail option instead of the slim version – although that always sounded right for dinos anyway. Hmm,…

  • RPG science: Designing dinosaurs just got easier?

    23Dinosaurs may not have been as heavy as previously thought. Those are the words of scientists who found flaws in the models used to estimate weight: “Palaeontologists have for 25 years used a statistical model to estimate the body weight of giant dinosaurs and other extraordinarily large extinct animals,” said Gary Packard, from Colorado State University, whose research will appear in the Zoological Society of London’s Journal of Zoology this week. “We have found that the statistical model is seriously flawed and the giant dinosaurs probably were only about half as heavy as is generally believed.” In other words, dinosaurs are just as big – long and tall, that is…
