Abstract

Late Tremadocian radiolarian faunas were first recovered from the Cow Head Group, Newfoundland, Canada. Three faunal assemblages were recognized, one from Martin Point and two from Western Brook Pond in Gros Morne National Park. These radiolarian faunas include six families, 11 genera, and 26 species. In these faunas, six genera (Archeoproventocitum, Cowheadia, Neopalaeospiculum, Protospongentactinia, Protoproventocitum and Westernbrookia) and 17 species (Archeoproventocitum nudiformum, A. retiformum, Aspiculum densum, A. jamesi, A. multistratum, A. gigantium, Cowheadia duplextesta, Neopalaeospiculum densum, N. laxum, N. transformum, Pararcheoentactinia stilla, Protospongentactinia spongiosa, Protoproventocium nazarovii, P. aitchisoni, Westernbrookia cancella, W. diversa, and W. ovata) are new. Late Tremadocian faunas are characterized by the appearance of proventocitiids and diversification of aspiculumids and reduction of protoentactiniids and echidniniids that had flourished in the early Tremadocian faunas. An examination of the biostratigraphic range of co-occurring conodonts indicates that the radiolarian faunas described here belong to the late Tremadocian, from the Lower Diversity Interval through the M. dianae Zone to the lower P. proteus Zone. With the recovery of conodonts of the R. manitouensis Zone from other localities in the study area, the correlation among Martin Point, Western Brook Pond, Broom Point, and St. Paul's Inlet strata has became more precise. Also, the middle and late Tremadocian Cow Head Group can be subdivided into the R. manitouensis Zone, the Low Diversity Interval, and the M. dianae Zone of North America. The lower P. proteus Zone of the latest Tremadocian for northern Europe is recognized in the Western Brook Pond South section.

지금까지 보고된 하부 오르도비스기의 Tremadocian과 Arenigian에 속하는 방산충 군집들 간에는 유사성이나 연관성이 거의 보이지 않았다. Tremadocian에서 Arenigian의 방산충 군집의 진화경향을 알 수 없었던 이유는 후기 Tremadocian 방산충 군집에 대해 알려진 바가 없었기 때문이다. 캐나다 뉴파운드랜드의 Cow Head Group에서 후기 Tremadocian에 속하는 방산충 화석 군집들이 처음으로 발견되었다. 이 새로운 방산충 군집들은 모두 6과, 11속, 26종에 속한다. 이들 가운데 6속 17종이 새로이 발견된 것들이다. Arenigian에서만 보고되었던 Proventocitidae에 속하는 종들이 다양하게 산출되었다. 초기 Tremadocian에 번성했던 Protoentactiniidae와 Echidniniidae에 속하는 것들은 감소하고 Aspiculumidae에 속하는 것들은 더욱 분화되어 다양하고 풍부하게 산출되었다. 방산충과 함께 출현하는 코노돈트 연구로 Low Diversity Interval에서 M. dianae Zone 그리고 하부 P. proteus Zone에 속하는 후기 Tremadocian 방산충 군집들로 밝혀졌다. 또한 R. manitouensis Zone에 속하는 코노돈트 화석군집이 발견되어 중기와 후기 Tremadocian에 속하는 Cow Head Group이 분포하는 여러 지역 간의 (Martin Point, Western Brook Pond, Broom Point, 그리고 St. Paul's Inlet) 층서대비를 보다 정확하게 할 수 있었고, 코노돈트 생층서에서는 R. manitouensis Zone, Low Diversity Interval, M. dianae Zone, 그리고 하부 P. proteus Zone이 식별되었다.
