LM and TEM investigations on the Upper Cretaceous Ajkaite of Hungary II.
This paper presents the LM morphology of the woody remnants of the amber containing brown coal samples and the ultrastructure of a peculiar fossil angiosperm pollen grain. Based on the xylem remnants Pteridophyta, Cycadophyta, Coniferophytina, ancient dicotyledonous taxa and Palmae may be presumed....

| 520 | 3 | |a This paper presents the LM morphology of the woody remnants of the amber containing brown coal samples and the ultrastructure of a peculiar fossil angiosperm pollen grain. Based on the xylem remnants Pteridophyta, Cycadophyta, Coniferophytina, ancient dicotyledonous taxa and Palmae may be presumed. Among the Coniferophytina it is worth mentioning the lack of the Araucariaceae tracheids, because of the presence of the Araucariaceae pollen grains in the samples. The amber in the dicotyledonous vessel is evidence of the angiosperm origin of the Ajkaite. The perforation type of the vessel is printed in the fossil resin remnant. This kind of vessel occurs in the Cretaceous and at the Magnoliaceae, and particularly in the Amentiflorae. The new TEM data, which are concerning the genus Complexiopollis KRUTZSCH 1959 em. TSCHUDY 1973, are different from the previously published ones. In the investigated specimen the protoplasm was not preserved. | |
