“…The specimen from Scania does not yield any cuticle, and therefore further assignment is not possible; it consequently should be considered as Taeniopteris. Independent of the specific assignment of these four specimens, Van Konijnenburg-van Cittert et al (2017) came to the conclusion that the name "Nilssoniopteris vittata (Brongniart 1828) Florin 1934" should no longer be used.…”

“…Placement in Cycadales, Nilssoniales or Bennettitales is warranted if the respective epidermal characteristics such as stomata and cell walls are known, with the exception of Nilssonia, where the mode of lamina insertion allows placement based on macroscopic morphology as well (see later), while assignment to marattialean ferns can be done if sporangia are preserved. If none of these features is available, such fossils are commonly placed in the fossil genus Taenio pteris (see Van Konijnenburg-van Cittert et al 2017).…”

“…In a recent study, Van Konijnenburg-van Cittert et al (2017) made an attempt to help palaeobotanists easily differentiate between several genera comprising such taeniopterid leaves; the authors also provided an elaborate taxonomic key to help determine the generic affiliation of such fossils.…”

“…If no cuticle is preserved or the cuticle is unknown, leaves are assigned to Tae niopteris. Preserved cuticle with cycadalean (haplocheilic) stomata identifies the leaves as belonging to either Bjuvia, Rhabdotaenia or Doratophyllum, while a bennettitalean cuticle with syndetocheilic stomata warrants assignment to either Nilssoniopteris or Nipaniophyl lum (see Van Konijnenburg-van Cittert et al 2017; but regarding Nipaniophyllum, see Pott et al 2017).…”

“…During that study of Van Konijnenburg-van Cittert et al (2017), the nomenclatural history of Taeniopteris, Taeniozamites and Nilssonio pteris was re-evaluated also. For all three genera, species carrying the epithet "vittata" had occasionally been considered types in the past, based on different or even the same specimens, complicating this issue even further.…”

ABSTRACT. We identified and located the type specimen of Scolopendrium solitarium, which is the basionym to what for decades was commonly referred to as "Nilssoniopteris vittata" and is now known as Nilssoniopteris solitaria (Phillips) Cleal et P.M.Rees. As Cleal and Rees (2003) never located and studied the type specimen of Scolopendrium solitarium and simply trusted Harris (1969), who included Scolopendrium solitarium in the synonymy of Nilssoniopteris vittata, it remained to be shown that this specimen indeed has bennettitalean affinities. Here we provide results of a cuticular analysis of the material and confirm the bennettitalean nature of Scolopendrium solitarium, and consequently that its placement in Nilssoniopteris solitaria is valid. Nilssonio pteris solitaria is, as a senior synonym of Nilssoniopteris tenuinervis, the type species of Nilssoniopteris. The name "Nilssoniopteris vittata" should no longer be used because it was based on Taeniopteris vittata, which is the conserved type of Taeniopteris, a genus in which taeniopterid fossils are placed if epidermal anatomy is unknown. Specimens identified as this species but yielding a bennettitalean cuticle should be referred to as Nilssoniopteris solitaria.

Analyses of coprolites provide important data on animal feeding and food quality, including information on the taxonomy of the biotope. Knowledge of the diet of extinct animals has implications for our understanding of the evolution of various physiological strategies and feeding adaptations. Here we provide the first description of plant remains preserved in coprolites from early Hettangian deposits at Sołtyk ow (Holy Cross Mountains, Poland). The coprolites probably originated from herbivorous sauropodomorphs, ornithischians and large carnivorous theropods, from which tracks are known from the site. Herbivorous coprolite producers fed on the flora growing on a fluvial plain, and the cuticles that remain in the coprolites originated from crowns of gymnospermous trees or shrubs. Coprolites assigned to large predators contained more diverse plant remains, although they also belonged to the gymnosperms. These were probably ingested together with the

A recently discovered Early Jurassic locality at Hicks Creek, Talkeetna Mountains, Alaska, yielded a macrofossil plant assemblage comprising predominantly bennettitaleans and ferns, accompanied by horsetails, seed ferns, cycads and conifers. Single species from different plant groups dominate the assemblage (e.g. Cladophlebis alata, Otozamites pterophylloides; less frequent Rhaphidopteris sp. and Pagiophyllum falcatum; sporadic Thallites sp., Klukia sp., Todites williamsonii, Coniopteris bella, Sagenopteris sp., Zamites sp., Nilssoniopteris pristis, Pseudoctenis sp., Eretmophyllum sp. and Elatides sp.). We also encountered a new foliage of cycadophyte type, Hanophyllum varioserratum gen. et sp. nov. Hicks Creek is one of four Alaskan areas with fossil Mesozoic plants that have been investigated. Along with rocks of Puale Bay and the East Fork of Boulder Creek exposures, this locality is of Early Jurassic age, while Cape Lisburne is Early Cretaceous (Albian). Based on a comparison of the floral composition of Hicks Creek with some other localities (Alaska and beyond), environmental conditions for the Peninsular terrane are inferred. Floristic differences between localities are explained by the varied topography, interpreted as disturbed coastal–lagoonal or as undisturbed, moist and warm inland. Some taxa (Todites williamsonii, Coniopteris bella, Nilssoniopteris pristis, Otozamites tenuatus, O. mimetes, Brachyphyllum crucis) common to the Alaska Peninsula and Middle Jurassic of Yorkshire may suggest a possible pathway of plant migration during the movement of the Peninsular terrane. The occurrence of Cladophlebis alata in the Lower Jurassic of south‐central Alaska and the Lower Cretaceous of northwestern Alaska may also shed light on the posited spread of this species.
