The Early Cretaceous tree fern Acanthopteris (Dicksoniaceae): New insight into fossil records, species diversity, palaeogeography and palaeoclimate
Acanthopteris is a fossil fern genus that was established by H.C. Sze in 1931 based on leaf remains from the Lower Cretaceous of the Fuxin Basin in Liaoning Province, China. Traditionally, Acanthopteris is considered to belong to the tree fern family Dicksoniaceae and has been mainly found in the Lower Cretaceous of Fuxin Basin, Huolinhe Basin, and other coeval basins in Northeast China. Since this genus was founded, five fossil species have been described, including A. gothani Sze, A. acutata (Samylina) Zhang, A. alata (Fontaine) Zhang, A. onychioides (Vassilevskaja et Kara-Mursa) Zhang, and A. szei Cao. Based on the investigations on the newly collected fossil specimens and the examinations of other specimens, a reassessment of the systematics and fossil record of Acanthopteris is performed by using both morphological and cluster analysis approaches. The emendation of generic diagnosis of Acanthopteris is provided herein. Geographically, Acanthopteris shows limited distribution in North and NE China, Siberia, Russia and the Inner Zone of Japan. Temporally, Acanthopteris is restricted to the Aptian-Albian period, representing a climate index fossil for a warm and humid climate condition of tropical to subtropical zones during the Early Cretaceous.
期刊介绍:
Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings.
Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale.
Research Areas include:
• Regional geology
• Stratigraphy and palaeontology
• Palaeobiology
• Palaeobiogeography
• Palaeoceanography
• Palaeoclimatology
• Evolutionary Palaeoecology
• Geochronology
• Global events.
