ABSTRACT
A late Middle–early Late Jurassic fossil plant assemblage recently excavated from two Callovian–
Oxfordian sites in the vicinity of the Daohugou fossil locality in eastern Inner Mongolia, China, was analysed in
detail. The Daohugou fossil assemblage is part of the Callovian–Kimmeridgian Yanliao Biota of north-eastern
China. Most major plant groups thriving at that time could be recognized. These include ferns, caytonialeans,
bennettites, ginkgophytes, czekanowskialeans and conifers. All fossils were identified and compared with species
from adjacent coeval floras. Considering additional material from three collections housed at major palaeontological
institutions in Beijing, Nanjing and Pingyi, and a recent account in a comprehensive book on
the Daohugou Biota, the diversity of the assemblage is completed by algae, mosses, lycophytes, sphenophytes
and putative cycads. The assemblage is dominated by tall-growing gymnosperms such as ginkgophytes, czekanowskialeans
and bennettites, while seed ferns, ferns and other water- or moisture-bound groups such as
algae, mosses, sphenophytes and lycophytes are represented by only very few fragmentary remains. The floral
composition underlines the Callovian–Kimmeridgian age of the Yanliao Biota. The Daohugou/Yanliao flora is
a typical member of the Middle to Late Jurassic Coniopteris-Phoenicopsis assemblage of north-eastern China,
differing from the Early Cretaceous Jehol flora. Both floras probably belong to the same cycle of volcanism and
sedimentation, although the Daohugou Bed is older than the Yixian Formation. The Yanliao fossil assemblage
is placed in a larger palaeo-phytogeographical context and its relationships with Middle–Late Jurassic floras
from north-eastern China, north-eastern and eastern Siberia and Japan are evaluated.
