Pyrite Fenestella acmea Bryozoan Fossil

 


Saturday I gave a talk at the Falls of the Ohio Interpretative Center entitled "Fossils Around Us - You Don't Always Have to Go to the Wilds of Nature to Find Creatures of the Past". This presentation was about fossils one can find in buildings and other human constructed objects. 

After finishing I checked out the Waldron Shale Fossil exhibit at the center. Lots of Silurian Period fossils to look at in the display case.

Highlighted in this post is a fossil called Fenestella acmea (Hall) bryozoan fossil. Fossil found in the Waldron Shale of Clark County Indiana USA. It dates to the Silurian Period. Very nice specimen as it is coated in pyrite.

Paleontologist Henry Nettelroth

Recently, I have been working on a presentation about the 1889 book Kentucky Fossil Shells by Henry Nettelroth (1835-1887). It is an impressive work for amateur paleontologist.

This biographic information appeared in the 1908 publication of Smithsonian Miscellaneous Collections Vol. V Quarterly Issue Part 2 in an article "The Nettelroth Collection of Invertebrate Fossils" by R.S. Bassler. 

Early Life

"Henry Nettelroth was born in the Kingdom of Hanover, on June 6, 1835. His family from a remote period were land-owners, inhabiting that portion of German territory, with estates located about the village of Nettelrode. Henry Nettelroth attended the German universities and was graduated as a civil engineer just before the war between Prussia and Hanover; he was an engineer officer in the Hanoverian army, but came to America shortly after the battle of Langensalza (1866). Here he took up the practice of civil engineering."

Career & Death

"His first employment as topographical engineer on the Elizabethtown and Paducah Railroad, then building, taking him to Kentucky, determined his subsequent location in Louisville. In that city he continued the pursuit of civil engineering, both active and consultant, until incapacitated by ill health a few years before his death. He became an American citizen, having immediately on his arrival in this country renounced allegiance to any European government. In 1867 he was married, in Louisville, Kentucky, to Emma Vassmer, also of Hanover. Mr. Nettelroth died on September 2, 1887."

Contributions to Paleontology

He had been interested in paleontology while still in his native country, and it was but natural that the collection and study of fossils should be continued in connection with a profession which offered such good opportunities. In his spare time, therefore, during more than fifteen years, he enthusiastically collected geological specimens, wisely limiting his cabinets principally to those fossils found in the immediate vicinity of Louisville and the Falls of the Ohio, but including, however, related specimens  from other sections of the country. His zeal in this pursuit stimulated the local interest in paleontology, and there appeared a number of collectors, several of whom became known later as capable and discriminating paleontologists. As a result of the enthusiasm of this coterie, a number of excellent collections were brought together and some rich beds and fossil-bearing strata were discovered which are now known universally to geologists.

Mr. Nettelroth's contribution to geological literature consists of a quarto volume of 245 pages and 36 plates, entitled "Kentucky Fossil Shells : A Monograph of the Fossil Shells of the Silurian and Devonian Rocks of Kentucky." This work, which was issued by the Kentucky Geological Survey in 1889, two years after the death of its author, is strictly biological in its scope. Over two hundred species of mollusca from the strata mentioned in the title were described and illustrated, in addition to a few Ordovician brachiopoda, sponges, and bryozoa. A short sketch of geology and paleontology, written for the general reader, introduces the purely descriptive part, but no particular reference is made to the geology of the Ohio Falls region. Forty-three new species were instituted by Mr. Nettelroth, the remainder being for the most part re-descriptions and illustrations of forms described by others in various scattered publications."

Legacy

After his death, two paleontological things happened. First, his reference to his best fossils was published by Kentucky Geological Survey in 1889. Second, his two sons, H.H. Nettelroth (1871-1936) and Dr. Alexander Nettelroth (1869-1952) of Louisville, Kentucky sold about 8,000 fossil specimens to the Smithsonian Institution and U.S. National Museum in 1907. The collection still exists today housed in the collections of the Department of Paleobiology, National Museum of Natural History, Smithsonian Institution.

As a point of Louisville interest, after Herman Nettelroth's wife Mary Aylett Buckner Nettelroth (1880-1957) died, she setup in her will that a trust be setup for charitable giving to certain causes in Jefferson County, Kentucky. The Courier Journal reported that after her husband died December 10, 1936 he left in his will $118,000 to her. After she died April 24, 1957 The Courier Journal reported her estate of about $600,000 set up the Herman H. Nettelroth Fund administrated by Citzens Fidelity Bank & Trust Company. The newspaper reported in an June 17, 1958 that the fund would create an one acre fenced bird sanctuary at Cherokee Park that would have a three-tier fountain and bird bath. It provided $500 to setup the sanctuary and about $150 each year for maintenance & bird seed.

The Fund would help with eight civic projects: bird sanctuary, "the providing for and equipping of children's playgrounds", "establishment and maintenance of day nurseries for working mothers", University of Louisville scholarships, "promotion of animal rescue work", money to buy children's books for public libraries, "support of the community chest", and "support of disaster-relief work of the Red Cross". 

As of 2019, the Herman H Nettelroth Fund had grown to $2.4 million in assets and distributed 8 projects totaling $134,000. PNC Bank now administrates the fund. This LINK will show who they distribute money to (e.g. U of L, Metro United Way, Louisville Free Public Library, YMCA)

Looking back at past Courier-Journal issues, an auction notice appeared in 1978 The Courier-Journal classified section listing. "LIQUIDATION OF SMALL ANTIQUE SHOP AND OTHER CONSIGNMENTS WED. July 19th, 1978 12 NOON... A collection of rocks and Indian arrowheads from the collection of Henry Nettelroth a noted Paleontologist of the Falls of the Ohio Region, included are Flint arrowhead, stone tools, igneous rocks, fossils, corals, etc. AUCTIONS UNLIMITED DOUG WEST AUCTIONEER" So it appears not all of the Nettelroth collection went to the Smithsonian. 

As of June 2023, one of his spiny snail Platyceras dumosum fossil specimens can be viewed at the PLAYING THE NUMBERS display of the first floor at the Smithsonian's Museum of Natural History.

Nautilus maximus Fossil


Nautilus maximus
(Conrad, 1838) cephalopod fossil found at the Falls of the Ohio, Indiana USA. It dates to the Devonian Period and was probably found in the Jeffersonville Limestone. This image is from the 1889 Kentucky Fossil Shells by Henry Nettelroth in Plate XXIV figure 1. 

This fossil is stored at the Smithsonian and was assigned catalog number: USNM PAL 51243.

Lituites marshi Fossil

 

Lituites marshi (Hall, 1867) ammonoid fossil found in Louisville, Kentucky USA. It dates to the Silurian Period and was probably found in the Louisville Limestone. This image is from the 1889 Kentucky Fossil Shells by Henry Nettelroth in Plate XXX figure 1. "Found in the Niagara rocks of the quarries east of the city of Louisville, where fragments of this shell are not rare, but fair specimens are not often found. In the speciment illustrated on plate 30, both termini of the shell are missing; it has preserved more than three complete volutions. The vacant central space indicates that, probably, two full volutions are obliterated there at the apex. How much there is destroyed at the other end can not be acertained, but that there is a large part of a volution missing can not be doubted. Thus it appears that the illustrated specimen, in its perfect condition, had six full volutions." Professor James Hall (1811-1898) named this species in honor of Professor Othniel Charles Marsh (1831-1899).

This fossil is stored at the Smithsonian and was assigned catalog number: USNM PAL 51378.

Here is a posting from 2009 of one of these fossils found in Louisville:
