Named in 1964 by Robert H. Moench and Robert Meyrowitz in honor of Marcus Isaac Goldman (11 January 1881, New York, New York, USA - 2 October 1965, Washington D.C., USA), sedimentary petrologist with the United States Geological Survey. He, along with A. C. Spencer, studied the Entrada Sandstone, the host rock at the type locality.
