August 17, 2008 - Cretaceous - Dallas and Perry Counties, Alabama

Day 1 Friday         Day 2 Saturday         Day 3 Sunday

A weekend trip to the Cretaceous chalk gullies of Dallas County Alabama and a creek in Perry county turned up numerous fossils.  Ancient creatures, including shark, turtle, mosasaur, ptychodus, fish, clam, and ammonite were found during the three day weekend trip.

DAY 3 - SUNDAY

After a good night's sleep, we headed off to a set of larger gullies early Sunday morning. A lot of fish bones, shark vertebra, shark teeth, enchodus jaw/tooth, nice piece of turtle shell, and even crocodile bones were found.  As usual, we stayed in the gullies until darkness made it impossible to collect any more.
