The Encyclopedia of Alabama includes about two dozen short articles about the geology of the state. Including this one, about the Steven C Minkin Paleozoic Footprint site, in Walker County. This site is one of the best in the world for its abundance and diversity of trace fossils:
http://www.encyclopediaofalabama.org/article/h-1371
The encyclopedia is written for the general public.
Here are photographs of some of the fantastically preserved trace fossils found at the site:
Insect jumping traces.
Horseshoe crab trackway.
Two crossing millipede trackways.
Amphibian trackway.
Reptile trackway.
Giant amphibian footprint next to a small trackway of a different amphibian.
Fish fin trails.
Insect wing impressions.
Trigonotarbid, an ancient spider relative.
A new book about these exciting Pennsylvanian trace fossils describes their discovery, their makers, and the environment in which they lived:

313 million-year-old trace fossils. Attenosaurs were reptile-like amphibians. This footprint is about the size of an adult human hand. The amphibian trackway is called Nanopus reidiae. Its maker would have looked like a salamander. There is a third trace fossil on the slab. Can you find it?
Read a lot more about this in our book "Footprints in Stone."

Back in 1930, George Gaylord Simpson, of the American Museum of Natural History in New York City, collected some rare and fantastic reptile trackways in Alabama. The tracks were more than 300 million years old, but they disappeared, and were never seen again. Never, that is, until a present curator of the museum, Carl Mehling, looked at the book that Ron Buta and I wrote about the Alabama tracks, entitled "Footprints in Stone." He realized that the unlabeled crate of tracks he had found in a storeroom were the missing set from almost 90 years ago. A mystery from the last millennium: solved! I must confess that my contribution to this discovery was minimal: Ron did the historical research that went into the book.

Footprints in Stone, my book about Pennsylvanian tracks in Alabama, is now pretty cheap on Amazon (less than $30). If you are interested in trace fossils made by some of the earliest reptiles, and critters that lived with them, now is your chance.

APS
Monograph No. 2
Pennsylvanian
Footprints in the Black Warrior Basin of Alabama.
Vol.
2: The Ichnology of Multiple Walker County Tracksites
A
CALL FOR PAPERS
In
2005, the Alabama Paleontological Society (APS) published a
comprehensive monograph on the trace and body fossils
of the world’s most prolific Carboniferous (Coal Age) tracksite,
the Union Chapel Mine (now the Steven C. Minkin Paleozoic Footprint
Site) located in north-central Alabama. More than 2500 specimens of
trackways have been collected from this site, a discontinued surface
coal mine in Walker County.
APS
Monograph No. 1, Pennsylvanian
Footprints in the Black Warrior Basin of Alabama,
known informally as the “Blue Book,” was a citizen
scientist-professional collaboration that stood as the first major
attempt to research Coal Age vertebrate trackways
in Alabama since Museum Paper No. 9, Footprints
from the Coal Measures of Alabama,
published in 1930 by the Alabama Museum of Natural History and
written by Truman H. Aldrich, Sr. and Walter B. Jones.
The entire book can be accessed online at
kudzu.astr.ua.edu/monograph/monofiles/monofiles.html
Although
the Blue Book is still of great value, it was not long before its
interpretations needed to be revised and updated. For example, the
taxonomy and attribution of vertebrate trackways is still in flux,
while some “horseshoe crab” trackways are now thought to have
been made by wingless monuran insects. Other traces in the Blue Book
are still being debated and likely need further work. But in
addition, many more specimens have been collected from Walker County
since 2005 that have not yet been examined by any professional
ichnologist. An example is the large database of new material from
the Crescent Valley Mine near Carbon Hill, 23 miles west and a little
north of the Minkin Site. Other sites include the Sugartown and Fern
Springs Road mines, which have been visited many times by APS
members.
We
are calling for papers to be part of a second monograph prepared
under the auspices of the APS to accomplish the following:
- illustrate new and interesting specimens collected from multiple tracksites since 2005
- arrange for thorough expert examination of the new vertebrate and invertebrate trace fossil specimens, treating both kinds as having the same level of scientific value
- revise the interpretations in the Blue Book accordingly
- cover all the known tracksites in Alabama
- include analysis and illustration of important specimens of plant fossils found at these same sites
- provide a global view of life during the coal age in Alabama, with the idea of connecting the Alabama tracks to other sites in the US and Canada
- provide a venue for several new studies of UCM and CVM material that are already underway or planned

We
encourage scientists with a strong interest and experience in
Carboniferous trace fossils to contribute papers to this volume. A
significant number of Walker County trace fossils collected by local
amateurs and citizen scientists are housed in museums in Alabama,
including the Alabama Museum of Natural History, the McWane Science
Center, and the Anniston Museum of Natural History. The
database has continued to expand since the first “Track Meet”
(gathering of collectors to document and often donate their
specimens) held nearly 17 years ago at the Alabama Museum of Natural
History. The story behind the discovery and
re-discovery of vertebrate trace fossils in Alabama is told in
“Footprints in Stone: Fossil Traces of Coal-Age Tetrapods,” by
Ronald J. Buta and David C. Kopaska-Merkel, published in mid-2016 by
the University of Alabama Press. The book is available through both
amazon.com and the UA Press.
SUBMISSION
PROCEDURE:
- If you are interested in contributing a paper to the proposed volume, please send the editors a letter of intent indicating the topic you would like to focus on. This letter should be submitted by NOVEMBER 1, 2017.
- If accepted by the editors as a possible paper for the volume, the formal deadline for submitting the completed manuscript is DECEMBER 31, 2018. All papers should be submitted in Microsoft Word with illustrations in separate jpeg or tiff format. Line graphs should have a resolution of at least 300 dpi. Halftones should be well-focused and sharp.

Footprints in stone
The Last Hurrah of the Trace-Fossil Book Tour
Ron Buta and I will be talking to the Sierra Club in a couple of weeks about our book and about the Minkin Paleozoic Footprint site. This is the last stop in our "book tour," such as it is. (If you are within reasonable driving distance of Tuscaloosa, one or both of us would be happy to talk about Pennsylvanian trace fossils)
Research is still ongoing about many of the trace fossils that have been found in Alabama's coal measures, as they used to be called. I don't think many new coal mines will be opening any time in the near future, the long-term trends in energy-sector economics being what they are, but with thousands of specimens on hand already, there is plenty to do.
If you want to see photographs of some of the trace fossils, just search this blog for "footprints."

Updates and down dates
Dreams and Nightmares 105. Every subscriber and contributor copy has been mailed. If you are supposed to get one, and you don't get it this week, please let me know.
This is the last day you can nominate speculative poems for the Rhysling award.
In about a month, I will talk about mysterious ancient creatures to science teachers at the Alabama Science Teachers Association meeting. Some creatures leave bones or teeth, others leave only footprints or burrows. In the latter case, how do we learn about them? It turns out we can learn as much or more from tracks than from bones.

"Footprints in Stone" — 30% discount with coupon code
"Footprints in Stone," the book I wrote with Ron Buta about trace fossils in Alabama, is on sale from the publisher. Either print out the coupon below and mail it in, or call your order in and give them the discount code.
Trace fossils are any marks made by ancient animals that are not actually parts of their bodies. Footprints, burrows, borings, tail drag marks, and so on. It just so happens that a coal mine in Alabama turned into the most important trace-fossil site of its age in the world. This book is about the discovery and preservation of the site and about all the marvelous fossils that have been found there.
We wrote the book for the general public. It would be a great gift for any kid who likes fossils.
If you live in or near Alabama, it is not difficult to get permission to visit the Steven C Minkin Paleozoic Footprint site. The book should be interesting and useful to anybody interested in trace fossils, even if they don't live anywhere near Alabama.

Spoke about Pennsylvanian trace fossils to another group of retirees today. They really enjoyed it and had a lot of questions. Tomorrow night is national fossil day, and we will be there with a bunch of trace fossils to show kids and I hope many will be there. Today I'm also reviewing part of a master's thesis on cave geochemistry.

National Fossil Day
National Fossil Day will be celebrated on Wednesday, October 12. At the Alabama Museum of Natural History, in Tuscaloosa, this will take place from 4 to 6 PM. Various groups on campus and from around town will have tables and games ,mainly aimed at children. Anyone can attend for free. I will be there with some trace fossils from coal mines. These include footprints of reptiles and other sorts of creatures. Ron Buta and I will be signing copies of our book, "Footprints in Stone."

Signing Saturday
So, this Saturday, I will be signing "footprints in stone," along with my co-author Ron Buta, in the Barnes & Noble in Tuscaloosa, Alabama. We will be there from 1 until 5 PM and we are going to have some actual trace fossil specimens for people to look at

What I should be doing instead of writing this
Well, there is always my regular work. Plus, in a few weeks I will be speaking to the Birmingham paleontological society about fossil reefs. Not long after that I will be speaking to a group of seniors, taking a class about science for nonscientists, about trace fossils. That talk is more or less ready, but I last did the reef 113 years ago and it needs updating.

For our anniversary we went to a new restaurant, River. Perhaps you can guess where it is located. It was reported to be very good but somewhat pricey. On the plus side, I didn't think it was more expensive than half a dozen other places around town (We spent $55). The food was good, but not great. Specifically, I had shrimp and grits. The shrimp were wonderful and the grits were too mooshy. The special Parmesan chips tasted good but they were kind of crumbled and it was hard to pick up the smaller pieces. The decor was nice and the staff pleasant, and you can eat outside on the river. Of course, it was dark, and we couldn't see the river. It is located in an upscale strip mall, but once you get to the actual restaurant, that is not apparent. I give it a B.
The Jerusalem artichokes are blooming. The flowers look remarkably like sunflowers. We had a lot more rain this summer than we usually do. Normally a third to half of the Jerusalem artichoke stalks wither away, because they really need a lot of water. Even in years when we don't find the time to dig them to eat them, at least they brighten up the late summer garden.In addition, we have three kinds of roses blooming, cosmos, hyssop, zinnias, day lilies blooming again, mock orange blooming again, Turks hat, red honeysuckle blooming again, Kyria blooming again, rose of sharon, clematis, obedience plant, crepe myrtles, gardenias again. Climate change is really messed with the flowers' annual reproductive cycle.
The book signing for footprints in stone last night went very well. About 70 people showed up, and I think about two thirds of them bought books. Some were friends who just came out of solidarity. The Alabama Museum of Natural History went all out. There was an unusually large variety of snack food for such an event, and they really made a nice display of trace fossils from the Minkin site. Actual fossils, poster size reproductions of the color paintings from the book, and the video that film students made when they interviewed us about the project is playing on a miniature screen of a type I haven't seen before. The exhibit will stay up through Christmas, so there will be plenty of time for people to see it.
It was funny, because when we arrived, there were a whole bunch of people from the Press, including several I have corresponded with but never met. I also met a new geology professor at the University and some friends I hadn't seen in about a decade.
Each of us spoke for about 10 minutes and all in all we had a great time. The Press is trying to arrange some similar events elsewhere and whatever comes to pass I will definitely let you know.

Book signing today
So, the second signing for Footprints in Stone is tonight, at the Alabama Museum of Natural History at 6 PM. Come, if you can. I'm a little concerned because it is on the same weekend as the first home football game, and at the University of Alabama, football is the most important academic department there is. They close all the parking lots at 5 PM. They are going to let us and our millions of fans into one small parking lot behind the museum, but it will fill up fast. If anybody comes at all. So, if the good turnout I hope for comes to pass, people will have to hike over from a parking garage several blocks away. Maybe some of them will appreciate the opportunity for some exercise.

Fossil insect trackway
A small fossil insect trackway from the Minkin site in central Alabama. This is the ventral side of the slab, so footprints have positive relief. On the left, you see a shallow undertrack on a layer close to the original sediment surface. On the right, you see a deeper layer, on which the trackway was more shallowly impressed. Same trackway, same insect, but preserved slightly differently on different layers.
Want to know more about this kind of stuff? Here is a new book:

080816b– Including dreams and nightmares 103 and 104 update
I am going to be alone for a few days, although somebody in my position cannot afford to be left alone, so I really won't be. However, my wife has to go visit her father; he is not doing too well. There is reasonable hope for significant improvement, but at his age, it is best to be proactive about visiting.
All subscriber and contributor copies of dreams and nightmares 103 have now been mailed. If you don't have yours in two weeks, you should definitely let me know.
I have read and responded to most submissions to dreams and nightmares in the last few days. I expect to finish catching up tonight. The next issue, 104, is fall and I am reading for 105. I will begin laying out 104 tonight, or maybe tomorrow, depending on when I finish with submissions.
In the coming days. I also will be posting more trace fossil photographs in this blog. Hope they are not too boring. Conversely, if people would prefer I say more about them when I post the pictures, let me know. And we will be attending a reception & signing books September 9 at the Alabama Museum of Natural History here in Tuscaloosa. The museum is planning to unveil a new exhibit about the trace fossil site at the same time.
