The Coniacian leaf flora from the northeastern part of the Bohemian Cretaceous Basin

Popis výsledku v původním jazyce

The "Chlomek Beds" (an informal designation of the psammitic facies of the Brezno Formation, north-eastern part of the Bohemian Cretaceous Basin) yielded a poorly preserved megaflora, dated as Coniacian on the basis of co-occurring inoceramid bivalves. The flora is interpreted to have grown on the West Sudetic Island, a palaeohigh of the Central European Archipelago. Ferns are diverse both in terms of specimens and of taxa: Monheimia chlomekiana, Sphenopteris dubia, "Pteridoleimma" durum, and two unnamed species of Korallipteris. Conifers are very rare: only two twigs of Geinitzia reichenbachii have been found. Angiosperms are represented by 14 dicot fossil-taxa. Two of them, Debeya (Dewalquea) sp. and Dalbergites atavius, are referable to eudicots. The remaining 12 taxa are described as dicots incertae sedis: Laurophyllum? melanophyllum, L. acuminatum, Laurophyllum sp., Apocynophyllum fractum, Ettingshausenia superstes, Ettingshausenia sp., Celastrinites engelhardtii, Salicites petzeldianus, Dryophyllum geinitzianum, "Dryandroides" quercinea, Dicotylophyllum bohemicum, and Dicotylophyllum sp. 1. In comparison with the better-preserved coeval flora of the East Sudetic Island (Idzikow Beds), ferns are more diverse and conifers are less diverse. Angiosperm flora is of similar physiognomy and is interpreted as representing riparian forests dominated by laurophylls and trees with serrate leaves. Local differentiation of riparian forests is attested by mutual exclusion of two serrate-leaved species, either Dryophyllum geinitzianum (relatively common at Robec and Jedlova, absent at Ceska Lipa) or "Dryandroides" quercinea (relatively common at Ceska Lipa, absent at Robec and Jedlova).
