Description
Here is your chance to own a classic Fossil Dalmanites Trilobite from a classic site. A nice showy piece as well
harder to obtain fossils from the Erie Canal during winter drainage in Middleport, New York
Classic trilobite from the famous Rochester Shale Deposits of New York. But these are becoming extremely rare from this site.
This is a Small Dalmanites Trilobite Fossil and is quite rare, Smaller specimens like this one are not often found. But these Silurian Period fossils are becoming more rare as this quarry is beginning to play out. This specime3n was collected many years ago and comes from a private collection.
The Small Dalmanites Trilobite Fossil is another trilobite found during the digging of the Erie Canal. First found in 1839 in a gorge dug for the canal. The trilobite is oval shaped and at first glance, it is difficult to judge which is the cephalon and which is they pygidium. Having only 14-16 body segments, the Dalmanites Trilobite method of rolling up is much like that of a rolly polly closing-just folding over because of this it can protect itself from danger. The head and tail sections are quite smooth.
During the Silurian Period New York State was the bottom of a shallow sea. Because of it’s location near the equator many large storms like hurricanes formed. But these storms did not only stay in the water. They hit the land and washed mud into the sea and buried many animals. Once buried the animals began the process of becoming fossils. Because the mud was fine grained the fossils preserved very well.
Specimen was meticulously prepared using micro air abrasive technology. The trilobite is 15/16 inches long on an irregular shale matrix measuring 2 1/4 inches by 2 1/2 inches. The cephalon is slightly askew but the exoskeleton is thick and eyes clearly visible.
