Abstract
A lately recovered site of plant macrofossils Ludvíkovice in the České středohoří Mts. is situated on the hill of the Sokolí vrch belonging to the Děčín Formation, which is radiometrically dated to 30.8-24.7 Ma, according to the regional stratigraphy. The flora has yielded a fern Rumohra recentior and several angiosperms, but no conifers.
The prevailing foliage is preserved without cuticles. Noteworthy are records of Daphnogene cinnamomifolia, Laurophyllum cf. acutimontanum, Platanus neptuni, Sloanea artocarpites, Carya fragiliformis / C. quadrangula, Alnus rhenana, Trigonobalanopsis rhamnoides, Eotrigonobalanus furcinervis and cf.
Quercus sp. Several foliage specimens of dicots have not been identified to species level, i.e.
Leguminophyllum sp., Pungiphyllum cf. cruciatum and Dicotylophyllum sp. div. The fossil plant assemblage of Ludvíkovice corresponds to zonal mesophytic vegetation accompanied by riparian elements, which is corroborated by the Integrated Plant Record vegetation analysis, which reconstructs a zonal broad-leaved evergreen forest close to living broad-leaved evergreen sclerophyllous forest from Southern Hunan and Northern Guangxi from SE China.
The vegetation thrived under humid climate characterized by average values of MAT (14.6-24.1 °C), WMT (24.7-28.3 °C), CMMT (2.2-18.8 °C) and MAP (979-1724 mm). The fossil flora of Ludvíkovice is similar in composition to the floras of Markvartice, Veselíčko, all from the Oligocene Děčín Formation of the České středohoří Mts. and Hrazený.
