Origin of the Modern Terrestrial Vertebrate Food Chain
ABSTRACT The Bromacker vertebrate fossil assemblage is strikingly unique compared to those of the highly fossiliferous, widespread Early Permian deposits of the USA in exhibiting: 1) total absence of aquatic and semi-terrestrial forms, 2) greatly reduced abundance and diversity of basal synapsids (“pelycosaurs”) that fulfilled the role of apex predators, and 3) high abundance and diversity of terrestrial herbivorous taxa. That is, the composition of the Bromacker vertebrate assemblage and the relative abundances of its taxa are difficult to reconcile with current knowledge of the well-documented examples of the Early Permian mixed aquatic-to-terrestrial trophic systems in the USA. The explanation given here for these unique paleobiological features is that the vertebrate assemblage reflects an adaptation to a rarely encountered paleoenvironment, the small, far inland, isolated, internally drained Tambach Basin. It is hypothesized that the Early Permian Bromacker assemblage is unique in representing an initial stage in the evolution of the modern terrestrial trophic system or food chain.
期刊介绍:
Annals of Carnegie Museum is a quarterly journal that publishes peer-reviewed short and medium-length original scientific contributions in organismal biology, earth sciences, and anthropology, in 40 by 52.5 pica format (168 by 220 mm or 6-5/8 by 8-5/8 inches). Subject matter must be relevant to Carnegie Museum of Natural History scientific sections or Powdermill Nature Reserve (PNR), preferably with connection to the Carnegie collection and/or personnel. Carnegie Museum staff and research associates receive publication priority, but others are encouraged to submit papers, especially those manuscripts explicitly based on the Carnegie collection.
