Anatomy, palaeoautecology and phylogenetic affinity of tubular Glossolites magnus from the early Cambrian Chengjiang biota, South China
A number of well‐preserved fossil taxa from the early Cambrian Chengjiang biota of South China have played important roles in the construction and analysis of the early evolutionary tree of metazoans. Certain other Chengjiang taxa, erected based on limited characters, have yielded little or no information concerning key aspects of their palaeobiology, and consequently their phylogenetic significance has been difficult to assess. One such taxon is the large conical animal Glossolites magnus. Exceptionally preserved new material of this soft‐bodied species herein, bearing oral tentacles and internal structures, indicates that G. magnus is not, as previously proposed, a hyolith. This work provides further information about possible biological affinities and palaeoautecology, which still remain open questions.
期刊介绍:
Papers in Palaeontology is the successor to Special Papers in Palaeontology and a journal of the Palaeontological Association (www.palass.org). The journal is devoted to the publication of papers that document the diversity of past life and its distribution in time and space.
Papers in Palaeontology is devoted to the publication of papers that document the diversity of past life and its distribution in time and space. As a sister publication to Palaeontology its focus is on descriptive research, including the descriptions of new taxa, systematic revisions of higher taxa, detailed biostratigraphical and biogeographical documentation, and descriptions of floras and faunas from specific localities or regions. Most contributions are expected to be less than 30 pp long but longer contributions will be considered if the material merits it, including single topic parts.
The journal publishes a wide variety of papers on palaeontological topics covering:
palaeozoology,
palaeobotany,
systematic studies,
palaeoecology,
micropalaeontology,
palaeobiogeography,
functional morphology,
stratigraphy,
taxonomy,
taphonomy,
palaeoenvironmental reconstruction,
palaeoclimate analysis,
biomineralization studies.
