gregladen | April 5, 2013A couple of years back, the The Crossley ID Guide for Eastern Birds came out and it caused a huge splash in the birdwatching world. For some time now it has become apparent that bird watching, especially the identification part of it, was changing in its approach. We describe it this way, though I think the reality is more complex: In the old days we used logical links to known reliable field marks to turn carefully made field observations into species identifications of varying degrees of certainty. Now, a new approach has been developed where we look at the whole bird and get an…

After being confronted with such imagery time and time again I didn't think twice about the pack-hunting behavior in Deinonychus as a kid, but I started to wonder on what evidence all these gory illustrations were based. The popular books in my own library treated the behavior as a fact and gave…
laelaps | October 13, 2007What do you get when you put dinosaurs, terrorists, and Navy SEALs all in one place? The answer in "A mess," and in this case such a disaster carries the title Raptor Island. Starring Lorenzo Lamas, the film continues the long standing tradition of putting guns and monsters in the same place in the hopes that something good will come out on film. Indeed, it seems that more effort is required to serve up a plate of Hamburger Helper than was put into the story and dialog of this slice of movie cheese, and its painfully apparent from the very first scene.
