A New Species

New records of Late Triassic reptiles from the Chinle Formation of Arizona include a new species of small trilophosaurid, a sphenodontid, and two taxa of eolacertilians. ?Trilophosaurus jacobsi n. sp. is a small trilophosaurid showing affinities to the type of Trilophosaurus buettneri of the southwestern United States and Variodens inopinatus from the Upper Triassic of Great Britain. A sphenodontid is also reported along with maxillae tentatively referred to the Kuehneosauridae and a jaw fragment from a subpleurodont eolacertilian with polycuspate teeth.

Vertebrate Assemblage

The Moncure microvertebrate locality in the Cumnock Formation, Sanford sub-basin, North Carolina, dramatically increases the known Late Triassic age vertebrate assemblage from the Deep River Basin. The ∼50,000 recovered microvertebrate fossils include osteichthyans, amphibians, and numerous lepidosauromorph, archosauriform, and synapsid amniotes. Actinopterygian fossils consist of thousands of scales, teeth, skull, and lower jaw fragments, principally of redfieldiids and semionotids. Non-tetrapod sarcopterygians include the dipnoan Arganodus sp., the first record of lungfish in the Newark Supergroup. Temnospondyls are comparatively rare but the preserved centra, teeth, and skull fragments probably represent small (juvenile) metoposaurids. Two fragmentary teeth are assigned to the unusual reptile Colognathus obscurus (Case). Poorly preserved but intriguing records include acrodont and pleurodont jaw fragments tentatively assigned to lepidosaurs. Among the archosauriform teeth is a taxon distinct from R. callenderi that we assign to Revueltosaurus olseni new combination, a morphotype best assigned to cf. Galtonia, the first Newark Supergroup record of Crosbysaurus sp., and several other archosauriform tooth morphotypes, as well as grooved teeth assigned to the recently named species Uatchitodon schneideri. Synapsids represented by molariform teeth include both “traversodontids” assigned to aff. Boreogomphodon and the “dromatheriid” Microconodon. These records are biogeographically important, with many new records for the Cumnock Formation and/or the Newark Supergroup. In particular, Colognathus, Crosbysaurus, and Uatchitodon are known from basins of Adamanian age in the southwestern U.S.A. These new records include microvertebrate taxa more typical of non-Newark basins (abundant archosauriforms, temnospondyls, lungfish) as well as more typical Newark osteichthyans and synapsid-rich faunal elements.

The Upper Triassic (Carnian-Norian) Filicopsida fossils present in the marine and continental outcrops, informally nominated as Santa Juana formation in the Biobío Region of Chile (37ºS/73ºS), are described. The taphoflora includes ten species, out of which eight are first registers for this area: Gleichenites quilacoyensis Leppe and Moisan sp. nov., Asterotheca rigbyana rigbyana Herbst, Rienitsia colliveri Herbst, Dictyophyllum fuenzalidai Herbst, Dictyophyllum (Thaumatopteris) rothi Frenguelli, Chansitheca argentina Herbst, Cladophlebis kurtzi Frenguelli and Todites baldoni Herbst ; three are new records for the Chilean Upper Triassic: Rienitsia colliveri Herbst, Gleichenites quilacoyensis Leppe and Moisan sp. nov., and Chansitheca argentina Herbst. The fern species found represents an 18% of the total specific diversity of plants in the Upper Triassic rocks from Biobío and help to understand the complicate floristic evolution of the communities in Gondwana. The Triassic rocks from Biobío are situated in the context of the Southwestern Extratropical Gondwana. The assemblage was developed in a continental environment with strong marine influence, under a rainy seasonal weather and displays age affinities with the argentinian Florian stage (Norian-Rhaetian). On an evolutionary point of view, the paleoflora was involved into the long Triassic/Jurassic mass extinction process, that means the end of the 'Dicroidium Flora' and the start of several elements that will dominate during the Jurassic.

Hells Canyon

Two Upper Triassic sphinctozoan sponges of the family Sebargasiidae were recovered from silicified residues collected in Hells Canyon, Oregon. These sponges areAmblysiphonellacf.A. steinmanni(Haas), known from the Tethys region, andColospongia whalenin. sp., an endemic species. The latter sponge was placed in the superfamily Porata by Seilacher (1962). The presence of well-preserved cribrate plates in this sponge, in addition to pores of the chamber walls, is a unique condition never before reported in any porate sphinctozoans. Aporate counterparts known primarily from the Triassic Alps have similar cribrate plates but lack the pores in the chamber walls. The sponges from Hells Canyon are associated with abundant bivalves and corals of marked Tethyan affinities and come from a displaced terrane known as the Wallowa Terrane. It was a tropical island arc, suspected to have paleogeographic relationships with Wrangellia; however, these sponges have not yet been found in any other Cordilleran terrane.
