“…125725′10.41″W). Beds at the quarry contain fossils of the collignonceratid ammonite Prionocycloceras (Haggart et al 2003;Karafit 2008;Karafit and Stockey 2008), a genus associated with sediments of Coniacian age (e.g., Young 1959Young , 1963Ward and Signor 1983;Matsumoto 1984;Zaborski 1990;Santamaria and Ricardo 1993).…”

Editor: Michael T. Dunn Premise of research. A new, morphologically distinct, anatomically preserved conifer assignable to the basal Cupressaceae, which was subject to arthropod infestation during life, has been discovered within a marine carbonate concretion from the Coniacian (Late Cretaceous) Eden Main locality of Vancouver Island, British Columbia.Methods. Specimens were studied from anatomical sections prepared using the classic cellulose acetate peel technique.Pivotal results. This plant, described as Acanthostrobus edenensis gen. et sp. nov., has helically arranged needle leaves and terminal seed cones composed of numerous helically arranged bract/scale complexes dominated by the bract. Both vegetative leaves and bracts display exceptionally long, narrow tips that may have been involved in predator deterrence. The seed cone has diminutive ovuliferous scales with free distal margins; bract/scale complexes bear two to four small, secondarily inverted ovules. Cone tissues contain arthropod feeding galleries surrounded by necrotic tissue and closing tissue (wound periderm) that proliferated throughout the specimen.Conclusions. The new plant is clearly attributable to basal Cupressaceae (Cunninghamioideae, Taiwanioideae, and Athrotaxoideae). While it shares features with extinct Jurassic and Cretaceous Cupressaceae, it exhibits a novel combination of characters that distinguishes it from previously described genera. This discovery expands our understanding of basal cupressaceous diversity and provides insight into conifer-animal interactions during the Cretaceous.

As so ci ate Ed i tor-Micha³ Zatoñ The clas si cal lo cal ity of Svinary in the east ern Bo he mian Cre ta ceous Ba sin is the site of new biostratigraphic in ves ti ga tions. Be sides some scarce macrofossil ev i dence, bulk sed i ment sam ples were pro cessed to re trieve micropalaeontological assem blages, and cal car e ous nannofossil smear slides were ana lysed. The stud ied ma te rial pro vided cal car e ous nannofossil as sem blages in clud ing Micula staurophora, Lithastrinus septenarius and Broinsonia parca expansa, thus doc u ment ing the Mid dle Coniacian (up per part of UC10 Zone and lower part of UC11 Zone). The foraminifera as sem blage is rel a tively rich, plank tonic spe cies show a wide strati graphi cal range, while the ben thic as so ci a tion rep re sented by Neoflabellina suturalis suturalis and Gaudryina carinata is very sim i lar to the Coniacian biozone of Stensioeina granulata-Eponides whitei, valid for the Bo he mian Cre ta ceous Ba sin. Ostracods are rep re sented by two com mon cytherellid spe cies, and two rare or na mented spe cies: Imhotepia marssoni? and Pterygocythereis spinosa. Inoceramid bi valves, namely Platyceramus mantelli, and a newly re corded ammonite, Tridenticeras tridens, sup port the late Mid dle Coniacian age of the Svinary out crop. New biostratigraphic re sults are given along with palaeo eco logi cal in ter pre ta tions of newly col lected fos sil ma te rial.
