Archaeology of the Reelfoot Basin -- July Adult Presented By Bill Lawrence
07.01.2021: "Archaeology of the Reelfoot Basin": Reelfoot Lake, in northwest Tennessee, was created by the New
Madrid seismic events of 1811 and 1812. Well known for its nesting and wintering population of bald eagles, Reelfoot Lake is also home to a dense concentration of prehistoric archaeological sites. This presentation will examine the archaeological record of this unique area and discuss the role that the New Madrid seismic events played in the preservation of small prehistoric earthworks.

Who Are The Native Americans And Where Did They Originate?
03.04.21: MIKE BALDWIN: Before the first European explorers set foot on the shores of North and South America, there were people here. It is suggested that man appeared in Asia around 35,000 years ago. Further evidence suggests that man arrived in North America around 14,000 years ago. Recently, new evidence has surfaced. We will talk about that and much, much more during the March MAGS Zoom meeting. To learn more about upcoming MAGS events and much, much more, check out the March Rockhound News.

What zircons in sedimentary rocks can tell us about plate tectonic processes
02.04.2021: DR. WILL JACKSON, DEPT OF EARTH SCIENCES, UNIVERSITY OF MEMPHIS: Detrital zircons are common accessary minerals in sandstone and conglomerate rocks. Zircons also represent the ideal mineral for calculating U-Pb ages. To investigate the development of the Tibetan Plateau, the largest and highest plateau on Earth, we dated zircons from syntectonic sedimentary deposits in southwest Sichuan Province, China. To learn more about Dr. Jackson work with zircons and much, much more, check out the February Rockhound News.

"In Defense of Rocks"
05.08.20: WC McDaniel: All MAGS activities were cancelled for the month of May. In the meantime, enjoy the newsletter and let us know if you have been able to incorporate your love of rocks into your everyday activiites during this time. Hear are some of my thoughts in defense of rocks. The use of the phrase “Dumb as a Rock” appears to be on the increase, especially by politicians, and it is time to stand up for rocks. I love and adore rocks, collect them, play with them, hoard and board them, display them, sell them, and put them to work. But I have never met a dumb rock. Met a few that were hard and somewhat ugly and of little use, some made my back ache and few that tried to remove my big toe. But through it all, they were rocks, not dumb rocks.

RECENT ABSTRACT ADDED TO MAGS REPOSITORY OF ARTICLES
Survey of Florida's Invertebrate Marine Fossils by David H. Hanes
- During the Cenozoic Era, the geologic and stratigraphic history of the State we now call Florida left invertebrate fossils that reflected the rise of a diverse marine fauna.
- Two geologic formations, the Tamiami and Caloosahatchee, were deposited through central and southwest Florida.
- This article focuses on a small sample of invertebrate fossils that reflect the form and shape of their extant fauna. Gastropoda and Mollusca marine fossils found in Tamiami and Caloosahatchee formation shell pits survived the moving shorelines of Florida during the Pliocene and Pleistocene Epochs.
- Surveys completed by the US Department of the Interior detected significant traces of rare earth elements, brought by ground water movement. At one fossil site in central Florida, fossils were transformed by the same ground water movement into beautiful mold aggregates of calcite crystals.

King Mastodon Excavation
01.05.2020: MATTHEW LYBANON: The King Mastodon Site is named after George King, who brought some large bones to the Arkansas State University Museum in April 1999. Dr. Julie Morrow, Station Archaeologist at the Arkansas State University-Jonesboro station of the Arkansas Archaeological Survey will be talking to us at the January MAGS membership meeting about this excavation.

FROM THE NOVEMBER 2019 MAGS YOUTH PROGRAM
Who Are the Native Americans and Where Did They Originate?
10.31.19: MIKE BALDWIN: The November MAGS Youth Program was presented by Mike Baldwin and youth member, Fulton Ledbetter [who spoke about the Mayan civilization and culture]. Native Americans are not Indians. Native Americans are the indigenous people of North and South America. Indigenous means the first [the original] people that inhabit an area, or continent. The term "Indian" originated when Christopher Columbus reached the Antilles islands and mistakenly thought he had reached the Indian Ocean. He labeled the inhabitants as "Indians" and the term stuck. Join the MAGS youth on November 8 as we learn about and discuss the indigenous people of the western hemisphere. To learn more about upcoming events and programs, check out the November Rockhound News.

Chucalissa Display Case and Native American Pottery
07.04.19: MIKE BALDWIN: This beautiful display case and the pottery housed in it are the result of a collaboration between the Memphis Archaeological and Geological Society and the C.H. Nash Museum at Chucalissa. The pottery inside this case has not been viewed by the general public until now. All the pots were found during excavations at the Chucalissa Indian Village years ago. The case was dedicated to the memory of 21-year MAGS member, Sherri Baldwin on Saturday, July 6. Read about this and other MAGS activities in the July issue of Rockhound News.

Lower Devonian Fossils of West Tennessee
The 50mm-wide specimen represented here is Dalmanites retusus. Known only from isolated pygidia. The pygidium is distinct from other Birdsong trilobites in that it has a rounded profile and lacks a pygidial spine.
Excerpt from Devonian Fossils of West Tennessee, by Kieran Davis.
The Lower Devonian system is well represented in Tennessee, forming part of an almost unbroken sequence of deposits ranging in age from the Middle Silurian to upper Lower Devonian. The Ross Formation of west-central Tennessee contains the most diverse and abundant Lower Devonian invertebrate fauna and this guide focuses on the most fossiliferous member of the Ross--the Birdsong Shale. The Birdsong Shale is well exposed in road cuts along State Highway 69 and in the many active and disused quarries of western Tennessee.

|Late Pleistocene Megafauna From Mississippi Plain Gravel Bars
Excerpt from Late Pleistocene Megafauna, by Dr. Nina L. Baghai-Riding, Danielle B. Husley, Christine Beck, and Eric Blackwell.
The late Pleistocene of North America is characterized by vertabrate animals (mostly mammals weighing ≥ 44kg) including Mammut americanum (American mastodon), Bison spp. (bison), Megalonyx jeffersonii, and Arctodus simus. Disarticulated skeletal elements of vertebrate fauna are frequently exposed on floodplain and gravel bar deposits after floodwaters retreat throughout the Mississippi Alluvial Plain.

|Survey of Florida's Invertebrate Marine Fossils
During the Cenozoic Era, the geologic and stratigraphic history of the State we
now call Florida left invertebrate fossils that reflected the rise of a diverse
marine fauna. Two geologic formations, the Tamiami and Caloosahatchee, were deposited through central and southwest Florida. Many researchers have
cataloged and documented the evolution of the fauna, and describe how the
regression of the Atlantic Ocean during the Cenozoic was the result of periods of glaciation and climatic warming that resulted in the changing shorelines, and the deposition of beds of invertebrate marine fossils.
This article focuses on a small sample of invertebrate fossils that reflect the
form and shape of their extant fauna.

Chucalissa Indian Village
CHUCALISSA (Choctaw word meaning "Abandoned House"): The ruins of this native American town sit on the Mississippi bluff five miles south of downtown Memphis. At one time the population of Chucalissa could have been a thousand to fifteen hundred. The town existed into the seventeenth century, when its townspeople left and never returned. Hence, the name Chucalissa. Since most native Americans north of the Rio Grande never developed a written language, we can never know the town's real name.
