Abstract
Antillean ichnology was essentially a blank book when Ron Pickerill of the University of New Brunswick, Fredericton, made his first research visit to Jamaica in February 1990. Ron’s first Jamaican trace-fossil research team worked initially on the Paleogene Richmond Formation, a flysch succession. Subsequent fieldwork examined the diverse sedimentary formations of the Neogene Coastal Group. Ron’s encyclopaedic knowledge of ichnotaxonomy and his enthusiasm for fieldwork led the team in many directions. Investigations were integrated with new studies of the island’s sedimentology and paleontology. For example, the description of the ichnology and sedimentology of the Upper Pliocene Bowden Formation, including the internationally famous Bowden shell bed, was part of a much wider study. The case-hardened rocks of the White Limestone Group discouraged detailed study until Donovan Blissett attacked the diverse ichnobiota of these user-unfriendly rocks for his doctorate under Ron’s supervision at the University of New Brunswick. Carriacou in the Grenadines was the other island to receive detailed examination in terms of its ichnofauna by Ron and his co-workers. The east coast of this small island provides a near-continuous exposure of the deep water succession of the Grand Bay Formation. Deeper-water burrows and borings in allochthonous bioclasts derived from the shallow shelf provide ichnological contrast in this formation.
1990年2月,弗雷德里克顿新不伦瑞克大学的Ron Pickerill首次对牙买加进行研究访问时,安的列斯群岛的技术基本上是一本空白的书。罗恩的第一个牙买加痕迹化石研究小组最初研究的是古近系里士满组,这是一个复理石群。随后的野外工作考察了新近纪海岸群的多种沉积地层。罗恩在技术分类学方面的渊博知识和他对实地工作的热情使团队朝着许多方向发展。调查与岛上沉积学和古生物学的新研究结合在一起。例如,对上新世鲍登组的技术和沉积学的描述,包括国际著名的鲍登壳层,是一个更广泛的研究的一部分。直到多诺万·布利塞特(Donovan Blissett)在新不伦瑞克大学(University of New Brunswick)在罗恩的指导下攻读博士学位时,研究了这些不适合人类使用的岩石的各种鱼生生物群,白色石灰岩群的硬化岩石阻碍了详细的研究。格林纳丁斯的卡里亚库岛是罗恩和他的同事们对其鱼动物群进行详细研究的另一个岛屿。这个小岛的东海岸提供了一个几乎连续不断的大海湾地层的深水序列。来自浅陆架的异域生物碎屑的深水洞和钻孔为该地层提供了技术上的对比。
