| Title: | New microconchiate Hybonoticeras from Mexico |
| Authors: | Oloriz, F
Villasenor, AB |
| Issue Date: | 1999 |
| Abstract: | A diversified and previously unknown record of microconchiate Hybonoticeras is analysed on the basis of the material collected in sections sampled bed-by-bed in the Mexican Altiplano. Five new species are described and compared to species traditionally recorded from the uppermost Kimmeridgian and the lowermost Tithonian in Europe. A general trend to smoothing in Mexican and European species during the earliest Tithonian is outlined. |
