Lepidodendron and Sigillaria

... while copying some mapping from the 'Laurel Highlands Trail' hikers guide a few posts ago, was lookin' at the guide section on 'Plant Fossils' - have a few good ones, actually...

... that's a 'Lepidodendron' - forgot to include a scale on these photos - for reference, that concrete wall the sandstone rock is settin' on is seven inches thick...

... here's what it looked like around 300 million years ago...

... a science lesson...

... this is a 'Sigillaria' - same seven inch wall...

... 300 million years ago...

... Sigillaria science - looks like the 'photo'd fossil' is part of the root system - never knew that until now - was no internet when I first found these years back and never looked 'em up - we've come along way in 300 million years (just ta' turn around and f*k it all up)...

... 'Chestnut Ridge' is loaded with this stuff (take a hike along 'Laurel Run') - a bit of 'Petrified Wood' as well - know a large boulder along the west flank of the 'Yough River' just south of 'Connellsville' that has an entire fossilized tree trunk running the length of it (about fifteen feet long as I recall) - have a photo of it somewhere, couldn't find it to include here - I'll hike back up and get another ... the 'Casparis Cliff' also has a pretty nice large 'Lepidodendrum' - everyone always thinks that it is a tire track from a dirt bike...

... tons of cool stuff on-line - this guy 'Walt Myers' is the best in our opinion (the following are copyright images from his website):




... Check out his stuff:

... the first time I checked it out it seemed like I was viewing for maybe twenty minutes - checked the clock - was almost two hours later...

... HA!... that last image could almost be a modern day 'Dunbar Creek' - minus the 'Eogyrinus' as well as the giant 'millipede' and flying "roachoid" - think 'muscle girl Sarah' (pictured above) would need to be packin' some "double-aught" bug spray if that were the case...
