Paratrochammina Minutissima n.sp. in brackish, marine-derived lakes of the Vestfold Hills, East Antarctica
Paratrochammina minutissima n. sp. is described fromAbraxas and Ace Lakes in the Vestfold Hills, EastAntarctica. The species is characterized by very small size(120 mm diameter), 4K chambers in the final whorl, weakadherence of particles to the tectin chamber lining and arelatively prominent prolocu...
