PERMIAN FORAMINIFERA AND ALGAE FROM GUATE MALA

From the Permian Chochal Formation in Guatemala (Central America), var ious taxa of Algae and Foraminifera are recognized. Described species are: dasycladales Clavaporella americana, Connexia slovenica, smaller foraminifera Neondothyra sp. and fusulinids Eoverbeekina americana, Ps eudoreichelina discoidea, Schubertella muellerriedi, Pseudofusulinoide s chixoyensis nov sp., Skinnerella gruperaensis, Parafusulina australi s, P. sapperi, P. guatemalaensis, P. fountaini, P. durhami and Skinner ina latina nov. sp. The whole Chochal Formation is Leonardian and Road ian in age, but with several noticeable diachronisms. Palaeogeographic ally, the Leonardian-Roadian seaway of the Guatemala extended from Tex as to Venezuela, and the Venezuelian area of Lake Maracaibo was adjace nt to the north of Guatemala (Maya Block). The dispersion of the fusul inids across Panthalassa has been favoured by surface currents, plant rafts and carbonate platforms on guyots and suspect terranes.
