October 2, 2004 - Lawrence and Colbert Co, AL
This field trip
to roadcuts in Lawrence and Colbert County, AL included
five stops during the
day. There were a number of students on the trip, who had
been
teased that "you're not going to find any fossils!". They
were
pleasantly surprised! After a long day of collecting, our
youngest participant, Bailey, decided she wanted to come on all our
trips!
Stop #1 was a roadcut in Lawrence County, Alabama, where large pieces of rugosa coral in Bangor Limestone had been excavated by road construction. The site has almost been totally reclaimed, but some very nice specimens were found.

Hunting for treasures. The site has become overgrown, making it more difficult to spot the coral pieces.

Stop #2 was a short stop, yeilding several samples of archimedes and crinoid stems, also from the Bangor Limestone.

Stop #3 was a roadcut in Colbert County. Horned corals, blastoids, and crinoid stems were plentiful.

The fossils weather out, and can be found laying on top of the ground.

Stop #4 was a different roadcut, and yeilded similar material as stop #3, such as archimedes, blastoids, brachiopods, and bryazoan fragments.

![cleaning limestone with acid wash](/system/files/images/04_sep_vl_4truck.jpg)
Greg is giving a short tailgate workshop on how to clean the limestone slabs found at this site with a light acid wash (that is not Diet Rite in that bottle!). Acid makes the fossils stand out nicely, but be sure to wear protective gloves and work clothes, and get proper training before trying this at home.
Stop #5 was also in Bangor Limestone, and provided a number of slabs containing broken bits of archimedes, blastoids, brachiopods, and bryazoan fragments. This site also contained numerous square brownish-red metallic crystals, which we believe to be pyrite. They are approximately 1/8 inch squares, some slightly larger.

On the way home, several of us decided to visit one of the local attractions.
![Coon Dog Cemetery](/system/files/images/04_sep_vl_6dogsign.jpg)
Yep, believe it. Only coon dogs buried here. Decoration day must have occurred recently. In addition to reading the tombstones, one can picnic under the covered pavilion or hike through the woods to the spring.
