Early crocodylomorph increases top tier predator diversity during rise of dinosaurs
(Springer Nature, 2015-03-19)
Triassic predatory guild evolution reflects a period of ecological flux spurred by the catastrophic end-Permian mass extinction and terminating with the global ecological dominance of dinosaurs in the early Jurassic. In ...
Armored kinorhynch-like scalidophoran animals from the early Cambrian.
Morphology-based phylogenetic analyses support the monophyly of the Scalidophora (Kinorhyncha, Loricifera, Priapulida) and Nematoida (Nematoda, Nematomorpha), together constituting the monophyletic Cycloneuralia that is ...
Chemical, experimental, and morphological evidence for diagenetically altered melanin in exceptionally preserved fossils
In living organisms, color patterns, behavior, and ecology are closely linked. Thus, detection of fossil pigments may permit inferences about important aspects of ancient animal ecology and evolution. Melanin-bearing ...
A vanished history of skeletonization in Cambrian comb jellies
Ctenophores are traditionally regarded as "lower" metazoans, sharing with cnidarians a diploblastic grade of organization. Unlike cnidarians, where skeletonization (biomineralization and sclerotization) evolved repeatedly ...
