ABSTRACT.?The large plagioptychid rudist bivalve Mitrocaprina tschoppi (Palmer) 
is recorded from the Guinea Corn Formation (Late Maastrichtian) of central 
Jamaica. ...'

Signor & Lipps at work again? <<

No, Zinsmeister.
Well, that's what I would call it. I believe it was Zinsmeister (et al.?) in a 
J. Paleont. paper about 1984/88 who first proposed that the KT mass extinction 
proceeded during the end-Cretaceous from the paleopolar regions towards the 
paleoequator. Thus ammonites became extinct in the Antarctic area some million 
years earlier than in the central Tethys.
