    be assessed Both groups have been intensively studied over the past 200 years and so should represent pinnacles in our knowledge of vertebrate systematic diversity We test the maturity of these datasets by assessing the completeness of their fossil records their susceptibility to changes in macroevolutionary hypotheses and the balance of their phylogenies through study time Catarrhines have shown prolonged stability with discoveries of new species being evenly distributed across the phylogeny and thus have had little impact on our understanding of their fossil record diversification and evolution The reverse is true for dinosaurs where the addition of new species has been non random and consequentially their fossil record tree shape and our understanding of their diversification is rapidly changing The conclusions derived from these analyses are relevant more generally the maturity of systematic datasets can and should be assessed before they are exploited to derive grand macroevolutionary hypotheses Download pdf Quick view Share Facebook Twitter Edit Delete Move section The fossil record of early tetrapods Worker effort and the end Permian mass extinction more by James Tarver It is important to understand the quality of the fossil record of early tetrapods Tetrapoda minus Lissamphibia and Amniota because of their key role in the transition of vertebrates from water to land their dominance of terrestrial more It is important to understand the quality of the fossil record of early tetrapods Tetrapoda minus Lissamphibia and Amniota because of their key role in the transition of vertebrates from water to land their dominance of terrestrial faunas for over 100 million years of the late Palaeozoic and early Mesozoic and their variable fates during the end Permian mass extinction The first description of an early tetrapod dates back to 1824 and since then discoveries have occurred at a rather irregular pace with peaks and troughs corresponding to some of the vicissitudes of human history through the past two centuries As expected the record is dominated by the well sampled sedimentary basins of Europe and North America but finds from other continents are increasing rapidly Comparisons of snapshots of knowledge in 1900 1950 and 2000 show that discovery of new species has changed the shape of the species level diversification curve contrary to earlier studies of family level taxa There is however little evidence that taxon counts relate to research effort as counted by numbers of publications and there are no biasing effects associated with differential study of different time intervals through the late Palaeozoic and Mesozoic In fact levels of effort are apparently not related to geological time with no evidence that workers have spent more time on more recent parts of the record In particular the end Permian mass extinction was investigated to determine whether diversity changes through that interval might reflect worker effort it turns out that most records of early tetrapod taxa when corrected for duration of geological series occur in the Lower Triassic Download pdf Quick view Share Facebook Twitter Edit Delete Move section Dinosaurs and the Cretaceous Terrestrial
