I just came across this image of a ladybug making tracks in condensation on a window. As far as I can tell, this is an original photo by user 77dlsd at reddit. Fascinating! This might be a decent way of capturing different kinds of arthropod trackways, although you may have to be something of a Snowflake Bentley to frost a glass plate, drop a critter, catch a critter, and photograph the plate without losing anything.

This weekend I’m getting back to working on Ichnowiki. The first article I found on my desktop was Milner et al. (2009) from PLoS ONE, so I started off with Anomoepus. If anyone else is interested in tracking down references and describing this taxon, by all means jump in!
Milner, Andrew R. C., Harris, Jerald D., Lockley, Martin J., Kirkland, James I. and Matthews, Neffra A. 2009. Bird-like anatomy, posture, and behavior revealed by an early Jurassic theropod dinosaur resting trace. PLoS ONE 4(3): e4591. doi:10.1371/journal.pone.0004591.
IchnoWiki is back up! Thanks to the Campus Dakota server. Check it out: IchnoWiki!
