Abstract

Many years ago Newberry (1876, 1888) reported the occurrence of leaves resembling Glossopteris, the typical Gondwana fossil, in the Late Triassic - Early Jurassic of northwestern Mexico and Honduras. Although, Glossopteris has been previously described a few times from areas like these outside the boundary of Gondwanaland the fossil occurs principally in the Permian and infrequently in the Early Triassic rocks of India and the southern continents, the now separated parts of Gondwanaland. The Glossopteris-like leaf from north-western Mexico is tentatively assigned to Glossopteris and the leaves from Honduras are assigned to Mexiglossa which was previously known only from the middle Jurassic of south-eastern Mexico.
