Pseudorbitoids from the Parguera Limestone, Puerto Rico, and from the Back Rio Grande Limestone, Jamaica, with remarks on the pseudorbitoidal evolutionary pattern

Abstract

Pseudorbitoides curacaoensis and P. israelskyi are described from two localities near Parguera, SW Puerto Rico, and P. trechmanni trechmanni and P. ?rutteni rutteni from respectively the Back Rio Grande and Rio Grande (Blue Mountain inlier, Jamaica). The evolutionary pattern of the pseudorbitoids is discussed on the basis of the present material and of samples described previously from Curaçao and from western Jamaica.
