EK. Goxpsmiru reports these minerals from the Ash Mari of the 
Cretaceous, a layer above the Green-sand. The mass of asphaltum 
weighed 100 pounds. The amber is stated to be related to the 
variety of succinite called Krantzite by C. Bergemann. Unlike 
ordinary amber its specific gravity is less than 1, and it fuses to 
a mobile liquid. ee amber is of occasional occurrence in the 
New Jersey Cretaceous; “sometimes hundreds of tons may be
