Chasing a Metallic Chimera?


For some reason I am obsessed with figuring out the name of the fish on the top of David Dale Owen's (1807-1860) last laboratory building located in New Harmony, Indiana USA. I posted about in an earlier December 30, 2018 blog entry, What is this Fish?

My current theory is that is not a fossil fish at all but a metal artist's creation. It appears to be be a cross between a carp (the body) and a herring (the fins) thus some sort chimera.

While researching it some more, I came across some 1934 historic American buildings survey images in the Library of Congress of New Harmony, Indiana, USA. They show the top of the conical roof with just a metal blastoid fossil. The Archimedes bryozoan screw fossil and fish are missing. So maybe the top was added later thus the fish was not significant. See orange arrow in image below.

Also the house has a little trilobite pattern at the top of some outside windows and doors. See the yellow arrows in the picture above and below.

The idea that the upper two fossils representations were added later after its 1859 completion was dashed by the entry in a book written by David Dale Owen's granddaughter, Caroline Dale Snedeker née Parke (March 3, 1871 – January 22, 1956). She gained some fame for writing fictional books for young people in the early 1900s.

One non-fiction book she wrote about New Harmony from stories told to her by her grandmother. It was called The Town of the Fearless and published in 1931. On page 348 she writes, "Also here is the New Laboratory, a charming building in English nineteenth-century style, which David Dale Owen built, and upon which he expended his artistic skill and loving fancy. On the spire of its little tower swings a geological fish as weather vane. Over its door is carved a trilobite. All this is in one plot of ground which is now a beautiful grove and a bird sanctuary."

So when the photos were taken in 1934 the weather vane must have been under repair. Of course, maybe the fish was changed out after being there for over 90 years.

The house has also been profiled by the Society of Architectural Historians at this page:

A Clam Fossil and Its Friends

 

Pictured above is a hash plate from the Calloway Creek Formation of Spencer County Kentucky USA. The main fossil is a mostly intact Caritodens demissa (Conrad, 1842) clam fossil with some interesting fossils on or around it. Below is unidentified 4mm diameter bryozoan fossil on the clam fossil.

Near the bryozoan on the shell is the 1.5 mm cephalon of unidentified trilobite fossil seen below.


Near by is the spine of an unidentified trilobite fossil measuring about 4 mm.

Off to the side of the shell is the pygidium of probably a Flexicalymene trilobite fossil about 5mm in size.

Thanks to Kenny for the pictures of his recent fossil find.

Pelecypod fossil originally described by Timothy Abbott Conrad in 1842 as Avicula demissa in "Observations of the Silurian and Devonian systems of the U.S., with descriptions of new organic remains" Journal of the Academy of Natural Sciences of Philadelphia, v. 8, no. 2, p. 228-235.

Fossils in the Media

 


Recently, while watching YouTube I saw two videos that were fossil related.

The first is a movie trailer for the film Ammonite starring Kate Winslet as Mary Anning, Saoirse Ronan as Charlotte Murchison, Fiona Shaw as Elizabeth Philpot and James McArdle as Roderick Murchison. I am not sure what to make of this movie. While excited a movie is being made of the famous fossil hunter Mary Anning I wonder if they focused too much on speculation about her private life and not on her contributions to the field of fossils. If you want to sell tickets, the film's writer, director, and producers probably took the path to achieve this. I will watch none the less just out of curiosity.

UPDATE (January 2021): I was able to watch the movie using Amazon.com and found the movie to be good but not historically accurate. It is probably not everyone's cup of tea but if you like stories from this time period or location it might be for you. The story centers on Mary Annings relationship with  Charlotte Murchinson. Referring to a book entitled Jurassic Mary: Mary Anning and the Primeval Monsters by Patricia Pierce (2015) [obtained at London's Natural History Museum's gift shop]. What I liked about the movie was Mary looking for fossils and prepping them. It also shows the bluntness of living in the early 1800s in England. They filmed on location in the winter of 2019 at Lyme Regis. One can see the challenging conditions in which to collect fossils in. The color tone of the movie is dark and dreary.

The main problem with the story is the real timeline is all a mess. It shows an older Mary (maybe in her 40s) interacting with a 20 something year old Charlotte. In reality, Charlotte (1788-1869) was 11 years older than Mary (1799-1847). Also Mary's interaction with Elizabeth Philpot in the movie puzzling as she appears estranged but in book it tells how they collected fossils together. It also documents that the Philpot sisters were known for a healing salve they made for the local community.

The movie credits lists geology consultants as David Tucker and Paddy Howe, geologist as Phil Stephenson. It thanks David Tucker of Lyme Regis Museum, David Roche Geoconsulting, and the Residents and Businesses of Lyme Regis, Dorset. It shows as filmed on location in Dorset, Kent, Surrey and London, United Kingdom.

According to the Jurassic Mary book, Charlotte visited Lyme Regis in 1825 with her husband and then stayed for 2 weeks to hunt fossils. The couple later invited Mary to stay with them in London in 1829. Mary visited London in 1829 (not sure the year is definitive) but it appears she did not stay with them. So when Mary met Charlotte she would have been 26 years old and Charlotte 37 years old. It would appear there would not be any romantic connection between the two of them. 

On a side note, Roderick Murchison (1792-1871) was Charlotte's husband and known for first describing the Silurian geologic time period. He also named the Permian Period after Perm, Russia in 1841. Also a new book about Ms. Anning has been published. The Dovecote Press has released THE FOSSIL WOMAN A Life of Mary Anning by Tom Sharpe October 2020.

Earlier this week I was watching clips from the December 5, 2020 Saturday Night Live (SNL). They usually open with political satire. Near the end of the skit they brought on cast members Pete Davidson and Kyle Mooney. When the character played by Pete Davidson was asked what was his current job was, he responded "I am curious about fossils." I am not sure what to make of this as a joke.

Glyptodon clavipes Fossil

This picture is of a Glyptodon clavipes (Owen, 1839) glyptodont fossil. It was found in Boliva. The fossil dates to the Pleistocene Epoch (1.8 million to 10,000 years ago). Named by Richard Owen (1804-1892) who is remembered as coining the term dinosaurs.

The fossil was on display in the Evolving Planet section of The Field Museum of Natural History in Chicago Illinois, USA as of August 2020.

Here is another one I saw at a special exhibit at that Museum of Natural History and Science in Cincinnati, Ohio in 2013. That fossil was found in Argentina.
