Abstract
Abstract This article presents a detailed description of insect trace fossils found in the megaflora of the Gzhelian-Asselian of the Bajo de Veliz. Plant-insect interactions are analyzed on 212 specimens of leaves from this flora, characterized by glossopterid (Gangamopteris, Euryphyllum, Glossopteris), cordaitales, sphenophytes, pteridosperms, lycophytes, conifers and seeds. Marginal feeding, surface and oviposition traces and galling predominate, as compared to the poor representation of piercing and sucking traces. Necrotic tissue was identified on leaves of the genera Euryphyllum, Gangamopteris, Glossopteris and bipinnate fronds of Botrychiopsis, suggesting that damage was produced while the plants were alive. The first reported evidence of galling for Botrychiopsis and piercings traces in Gangamopteris leaves for Gondwana are described.
Bajo de Veliz组(Gzhelian - Asselian)化石植物群中的植物-昆虫相互作用:阿根廷圣路易斯
摘要:本文详细描述了在巴约德韦利兹(Bajo de Veliz)的Gzhelian-Asselian巨型植物群中发现的昆虫痕迹化石。对该植物区系212份叶片进行了植物与昆虫的相互作用分析,其特征为舌蕨科(Gangamopteris, Euryphyllum, gloopteris)、珊瑚科、蕨类、蕨类、石松类、针叶类和种子。与刺穿和吸吮痕迹相比,边缘摄食、表面和产卵痕迹和磨蹭痕迹占主导地位。在蕨类植物Euryphyllum、Gangamopteris、gloopteris和Botrychiopsis的双叶上发现了坏死组织,表明这些植物在活着的时候就已经受到了损伤。首次报道了冈瓦纳Gangamopteris叶片上的刺穿痕迹和芽孢杆菌刺痛的证据。
期刊介绍:
The foremost aim of Ichnos is to promote excellence in ichnologic research. Primary emphases center upon the ethologic and ecologic significance of tracemaking organisms; organism-substrate interrelationships; and the role of biogenic processes in environmental reconstruction, sediment dynamics, sequence or event stratigraphy, biogeochemistry, and sedimentary diagenesis. Each contribution rests upon a firm taxonomic foundation, although papers dealing solely with systematics and nomenclature may have less priority than those dealing with conceptual and interpretive aspects of ichnology. Contributions from biologists and geologists are equally welcome.
The format for Ichnos is designed to accommodate several types of manuscripts, including Research Articles (comprehensive articles dealing with original, fundamental research in ichnology), and Short Communications (short, succinct papers treating certain aspects of the history of ichnology, book reviews, news and notes, or invited comments dealing with current or contentious issues). The large page size and two-column format lend flexibility to the design of tables and illustrations. Thorough but timely reviews and rapid publication of manuscripts are integral parts of the process.
