300-million-years-old cast iron cup from Oklahoma

This meticulously crafted piece of metal was unearthed in 1912 from a mine situated in Wilburton, Oklahoma.

The man who made this discovery was Frank J. Kennard, and according to his account, the object was found nestled within a substantial block of coal. However, the true enigma surrounding this cup lies in its perplexing age, a characteristic it shares with numerous other artifacts discovered across the globe, sparking considerable debate among researchers.

Such finds are categorized as out-of-place artifacts, often abbreviated as OOPArt, due to their inexplicable presence within geological strata where their existence is deemed chronologically impossible.

Throughout history, numerous such anomalous objects have been documented, yet the majority have vanished over time, leaving little trace of their existence.

The narrative of this particular artifact commenced in 1912 at a coal-fired power plant located in the town of Thomas, Oklahoma, USA.

During the process of preparing fuel, one of the plant’s workers encountered a piece of coal that was too large for conventional handling. Upon striking it with a sledgehammer to reduce its size, a small object resembling a bowl or pot was revealed within.

Subsequent examination of the discovered object determined that it was composed of cast iron, an alloy primarily consisting of iron and carbon.

Significantly, the surrounding fragments of coal retained a clear, solid imprint of the bowl, indicating that the object had been embedded within the coal for an extended period, allowing the coal to form around it.

Further investigation revealed that the coal seam from which this particular batch of coal originated was approximately 300 million years old.

To corroborate the authenticity of this remarkable find, a handwritten note penned by the very worker who discovered the bowl exists.

In this note, Kennard, who was identified as a Benton Co worker in 1948, stated: “While I was working in the Municipal Electric Plant in Thomas, Oklahoma in 1912, I came upon a solid chunk of coal which was too large to use. I broke it with a sledge hammer.

“This iron pot fell from the centre leaving the impression mould of the pot in the piece of coal. Jim Stall (an employee of the company) witnessed the breaking of the coal, and saw the pot fall out. I traced the source of the coal, and found that it came from the Wilburton, Oklahoma, Mines.”

The note concludes with the affirmation that Kennard was “Sworn in at Salpur Springs, Arkansas, November 27, 1948.”

Geological studies conducted on the coal deposits of the Wilburton Mine have repeatedly confirmed their age to be within the range of approximately 295 to 300 million years.

Unfortunately, the primary evidence supporting this extraordinary find rests solely on the testimony of an individual, which lacks the rigorous scrutiny of scientific validation. Consequently, this object, like many other similarly perplexing artifacts of comparable antiquity, has since disappeared without a trace.

The rediscovery of such an object today would undoubtedly offer invaluable insights into the circumstances of its discovery, its origin, the identity of its creator, and its intended purpose. Crucially, modern scientific analysis could potentially illuminate its true age with far greater precision.

One proposed theory attempts to explain the presence of such an object within ancient coal deposits by suggesting that mines, often containing pools of mineral-saturated water, could have eventually hardened, encasing any foreign objects that might have been present.

However, as noted by Mark Isaac, “The cup appears to be cast iron, and cast iron technology began in the eighteenth century. Its design is much like pots used to hold molten metals and may have been used by a tinsmith, tinker, or person casting bullets.”

The investigation into this intriguing artifact is hampered by the typical limitations associated with such discoveries: the reliance on anecdotal evidence as the primary source of information.

While Kennard’s account is compelling, it does not readily explain the artifact’s seemingly impossible embedding within coal that predates its apparent technological origin by approximately 300 million years.
