Description :
The planktonic foraminiferal species Globigerinoides ruber with pink-pigmented tests occupied a worldwide warm water belt during much of the Pleistocene. This variety was exterminated from the Indian and Pacific Oceans at about 120,000 yr BP, based on the oxygen isotope stratigraphy in 11 Indo-Pacific deep-sea cores, but it continued to live on to the present in the North and South Atlantic Ocean and the Mediterranean Sea. The disparate Atlantic and Indo-Pacific records reflect faunal provincialism that has been developing in the two regions after the emergence of the Panama Isthmus in the late Pliocene.
