The name was coined by T.A Conrad, 1839 in the New York State Geological Survey Annual Report. Named for the Helderberg Escarpment or Helderberg Mountains.

Very few fossils exist in the Shawangunk; however, Eurypterids can be found in the middle portions of the formation roughly 420–750 feet from the base in some locations in New York State. [5] Linguloid brachiopods were identified in the Lizard Creek Member. [1] The ichnofossil Arthrophycus was described in the Minsi Member in the area of ...
[43] In the first New York State Geological Survey, also begun that year, James Hall established the term "Marcellus Shale" in his 1839 report titled "Marcellus Shales in Seneca County." [44] Professor Hall also argued in 1839 against formulating geological names based on observed characteristics that may vary from place to place or need ...

Yngvar Isachsen of the New York State Geological Survey has found evidence strongly suggesting that the entire Panther Mountain region is the inverse form of a crater that formed after an ancient meteor impact when the Catskills were a river delta at the northeastern corner of the inland sea that is now the Allegheny Plateau. The rims of the ...
