Brevispirifer gregarius Brachiopod Fossil

 

This brachiopod fossil appears to be the Brevispirifer gregarius (Clapp). It was found in the Jeffersonville Limestone which dates to the Middle Devonian Period. The fossil was probably found around Louisville, Jefferson County, Kentucky. It was from the collection of Dr. James Conkin (1924-2017) with no label. The species name attributed to Dr. Asahel Clapp (1792-1862).

Rogers Clark Ballard Thruston - Louisville Geologist

My interest in this geologist stems from some fossil specimens found in Colonel Lucien Beckner's collection a Pennsylvanian Period gastropod found in the coal mines of eastern Kentucky and some gastropods from maybe the Eocene of Naples, Florida.

Early Years

Rogers "Rog" Clark Ballard was born on November 6, 1858 to Frances "Fanny" Ann Thruston (1826-1896) and Andrew Jackson Ballard (1815-1885) in Louisville, Kentucky, USA. He was born into a wealthy and prestigious family; his great-grandmother was George Rogers Clark (1752-1818) sister. Rogers began his early education at Hopkins Grammer of New Haven, Connecticut and then Williston Seminary of East Hampton, Massachusetts. After his freshman year of college, in the summer of 1877 he helped his father with mining interests in Colorado thus missing the start of his sophomore term.

He graduated in 1880 from the Sheffield Scientific School of Yale University with a degree of Bachelor of Philosophy. To round out his education, late in life the University of Louisville conferred a Master of Arts degree upon him in 1937 and the University of Kentucky awarded him a degree of Doctor of Laws in 1942.

Occupations

After graduating Yale, he started as a clerk for the Monon Railroad office in Louisville and worked his way up to Assistant Ticket Auditor. Later, he became a metallurgist for the Kentucky Geological Survey (KGS) on July 1, 1882. At the age of 25, on October 27, 1884, the Fayette County Court appended his mother's maiden name Thruston to his last name. His mother, the last of the Thrustons, wanted her family name to live on but as it turned out, he never married or had any children. He would sign paperwork with his initials RCBT or R.C. Ballard Thruston. 

 

Appears to be a Bellerophon meekianus gastropod fossil found by George Rogers Ballard Thruston in 1883 in a coal seam at Elkhorn Creek, Pike County, Kentucky.

He helped survey and photograph ("kodak") Pike, Letcher, Harlan, and Bell counties till he left the KGS in 1887. RCBT took employment with the Kentucky Union Land Company where he was buying land in Harlan and Bell counties as well as Wise and Lee counties in Virginia for coal and iron mining. By 1890, he was promoted to Superintendent of the Land Department where he worked on acquiring land for timber and coal in Estill, Powell, Lee, Breathitt, Perry and Letcher counties. In the 1880s, he and his brothers acquired acreage through the Interstate Investment Company in the Big Stone Gap section of Virginia for coal production. RCBT managed the Big Stone Gap Iron Company from 1895 to 1899.

As a side note, The Trail of the Lonesome Pine by John Fox, Jr. (1862-1919) was published in 1908. It became one of the best selling books in the United States in 1908 and 1909. The story takes place in the Appalachian Mountains of Virginia and Kentucky. Its main character is geologist John Hale who the author in part based on Rogers Clark Ballard Thruston. The story was adapted into a 1912 Broadway production, a 1916 Cecil B. DeMille film, a 1923 film and a 1936 film starring Fred MacMurray (1908-1991), Sylvia Sidney (1910-1999), and Henry Fonda (1905-1982). The author John Fox, Jr. was a friend to RCBT in 1890 where his family lived at Big Stone Gap, Virginia.

A colorized image from John Fox Jr. 1908 book The Trail of the Lonesome Pine showing the main characters mountain girl June Tolliver and geologist-engineer Jack Hale. It is thought heroine is based off a Keokee, Virginia girl Elizabeth Morris and the character Jack is partially based off of Rogers Clark Ballard Thruston who was a surveying geologist in the Big Stone Gap, Virginia area.

Retirement

In 1919, at the age of 61, Thruston retired with the intent to spending the rest of life studying history and traveling.

On November 18, 1921 he helped dedicate the Sunshine Ballard Cabin to Berea College. It was in honor of one of his relatives. The cabin allowed the school to expand its Fireside Industries department which taught weaving, basketry, homespun and hand work.

In 1922, he traveled to Naples, Florida, while there he found a number of gastropod shells (fossils?) known as Theodoxus reclivatus (Say, 1822) [modern name is Vitta usnea (Röding, 1798)].


 

In 1925, he participated in a history pageant in Lexington, Kentucky and dressed as his ancestor George Rogers Clark. He would spend the rest of his life promoting a monument be created to honor George Rogers Clark.

In 1930, he unveiled a monument to George Rogers Clark in Springfield, Illinois.

The Filson Historical Society

Today, the biggest impact Mr. Thruston left upon the Louisville area were his contributions to The Filson Historical Society (FHS). In 1919, he offered $50,000 to help the society obtain a fireproof room to store its collections. When the founder of the society, Reuben T. Durrett died in 1913, his family sold his historic collection the University of Chicago. RCBT went to Chicago to retrieve items that really belonged to the society and returned them to Louisville. He was president of the society from 1923 to 1946. In 1923, he helped the society purchase a new home and in 1929 covered half the cost of moving into it. 

He purchased F. W. Leach's research work The Genealogies of the Signers of the Declaration of Independence and donated to the FHS. His photo collection of over 20,000 images from 1880-1942 was also donated to the FHS collection. He contributed the following to the FHS History Quarterly

1926 The Signing of the Declaration of Independence 

1928 Letter by Edward Harris 1797 

1935 Some Recent Findings Regarding the Ancestry of General George Rogers Clark 

1937 Reprint of The Filson Club Program of June 25 1937 The Lincoln Pilgrimage

1940 Rachel Eastham Not Mary Byrd or Bird was the Wife of John Rogers The Grandfather of George Rogers Clark

1941 After the Death of George Rogers Clark

Legacy

He died at 2:15 a.m. at Jewish Hospital in Louisville, Kentucky on December 30, 1946. His funeral was held at Christ Church Cathedral followed by his burial at Cave Hill Cemetery. His remains are buried next to his parents in section G, lot 24, grave 12 at the cemetery.

RCBT left a very explicit 9 page will. 

Here is part of it, "As to the disposition of my remains after death. I am the holder of lots 24 and 25 in Section G, in Cave Hill Cemetery, Louisville, Kentucky. There are buried the remains of my maternal grand-parents and their children, my parents, a brother, my sister and certain law kin. The space next to the grave of my father has been set aside for my remains. There I have erected a headstone with an inscription complete except as to the dates of my death; that date I direct nay executor to
have suitably inscribed thereon.
My desire is that my body be cremated; that my ashes be placed in a simple glass, metal or pottery container and buried on the site above named. I also desire that all unnecessary forms and ceremonies be dispensed with and that the disposition of my remains after my death be accomplished simply, quickly and inexpensively."

As described above, his financial and research material contributions to the Filson Historical Society are probably most lasting mark on the Louisville area. In 1947, they devoted an entire issue of the History Quarterly to his memory. 

Besides the fossils I have documented earlier he also left specimens to old museum that was part of the Louisville Free Public Library which was later transferred to what is now the Kentucky Science Center. They are de-accessioning that collection so Thruston's items might now go to the Filson Historical Society or Frazier History Museum. The Speed Art Museum has some of his paintings including one called the View of Jerusalem from 1867.

He and his brothers donated a number of pieces of land to become parks: Ballard Square, Churchill Park and George Rogers Clark Park. In addition, they deeded the original home of George Rogers Clark on Poplar Level Road to the City of Louisville.

Cyclonema Snail Fossils

 

Pictures are of two Cyclonema (Hall, 1852) snail fossils found in Clark County, Kentucky, USA. They were probably collected in the 1930s by Colonel Lucien Beckner (1872-1963). The fossils date to the Ordovician Period. Colonel Beckner was a long time curator of the Louisville Museum of Natural History.

Halysites louisvillensis Chain Coral Fossil

 

This specimen is somewhat unique in what is normally found, it contains very visible mesocorallites quadrilaterals. It is described as a new species in Erwin Stumm's Silurian and Devonian Corals of the Falls of the Ohio on page 79 as Halysites louisvillensis (Stumm, 1964). Stumm writes about it, "The species is externally similar to Catenipora microparus (Whitfield) but differs in the presence of the very small mesocorallites."

Most of the specimens of chain corals I have seen, one cannot see the little square shapes in between the chain shapes. It is possible they are there but after hundreds of millions of years they blended together obscuring the four sided shape.

This fossil is found in the Louisville Limestone of Jefferson County Kentucky USA. It dates to the Middle Silurian Period.
