New System

A new system of nomenclature is proposed with the purpose of presenting a scheme which will be applicable to spores, pollens, and other microfossils from all geological ages. A review of previous nomenclatural systems is presented to indicate the historical development of microfossil nomenclature. The applicability of the new system is illustrated by naming 21 new species and four new genera of Upper Cretaceous microfossils from the Comox formation of Vancouver Island and the Oldman formation of southern Alberta. The microfossil conspecti are briefly compared with the assemblage previously reported from the Brazeau formation of western Alberta. Advantages of the new nomenclatural scheme are discussed in the light of future discoveries of plant microfossils, and their application to palaeobotanical and geological problems.

A New Species

Chasmosaurus irvinensis (sp. nov.) is distinguished from other species of this genus by the possession of a broad snout, absence of a brow horn (the position of which is occupied by a pit or rugosities suggestive of bone resorption), broadly rounded and open jugal notch, subrectangular squamosal, straight posterior parietal bar bearing 10 epoccipitals, eight of which are flattened, strongly curved anterodorsally, and nearly indistinguishably coossified to their neighbours, and small, transversely oriented parietal fenestrae restricted to the posterior portion of the frill. This species, restricted to the upper part of the Dinosaur Park Formation, is significantly younger than the other recognized Canadian Chasmosaurus species, C. belli and C. russelli. Phylogenetic analysis shows that C. irvinensis is most closely related to the other Canadian Chasmosaurus species and more distantly related to Chasmosaurus mariscalensis from Texas.

Incisive Foramen

Borealosuchus griffithi, sp. nov., is described on the basis of an incomplete skeleton from the basal Paleocene, southern Alberta. This new species records one of a few basal Cenozoic occurrences of Crocodylia so far known. B. griffithi is most distinctive in having a markedly laterally concavo-convex snout; a deep, elongate recess or fossa on the anteroventral surface of the jugal; and a large, nearly rectangular incisive foramen. Within Borealosuchus, B. griffithi probably takes a "more crownward" position than does B. sternbergii of the late Late Cretaceous. With additional information from the new species, the diagnosis of Borealosuchus is revised.

Abundant fossil cuticles are associated with megaspores in the Upper Cretaceous Whitemud beds of the southern Alberta plains and in the Whitemud Formation of the Cypress Hills. Form genera Spermatites Miner and Costatheca (Dijkstra) Hall are emended, and the new genus Carpotheca is described. The three genera are differentiated by shape and orientation of cuticular cells. Ten new species of seed cuticles are described. The affinity of Spermatites with the extant genus Juncus L. is reaffirmed, and it is suggested that Costatheca may be related to extant species of Butomus L. In the Whitemud, Costatheca is more abundant in the Alberta plains, whereas Spermatites and Carpotheca are better represented in the Cypress Hills. The fossil microfloral assemblage indicates that these beds were deposited in a continental, fluviatile to lacustrine environment, having a subtropical climate, in agreement with previous sedimentological, isotopic, and palynological investigations.
