Data from: Preservation of uropygial gland lipids in a 48-million-year-old bird

- O'Reilly, Shane
- DOI：
- doi:10.5061/dryad.7g1tb
- 摘要：
- or fossil feathers. By comparison with modern bird uropygial gland wax esters, we show that these molecular fossils are likely derived from endogenous
Data from:A large eagle (Aves, Accipitridae) from the early Miocene of Panama

- DOI：
- doi:10.5061/dryad.v1r28
- 摘要：
- We report the first Tertiary bird fossil from Central America, an ungual phalanx from a large, unknown genus and species of Accipitridae from
Data from: Extant-only comparative methods fail to recover the disparity preserved in the bird fossil record
- 负责人：
- DOI：
- doi:10.5061/dryad.p2d8k
- 摘要：
- simplified models of trait evolution without fossil data. Birds are a well-studied radiation, yet their early evolutionary patterns are still contentious
Data from: Egg shape changes at the theropod-bird transition, and a morphometric study of amniote eggs
- 负责人：
- DOI：
- doi:10.5061/dryad.s9227
- 摘要：
- geometry in a diverse sample of fossil and living amniotes using geometric morphometrics and linear measurements. Our goal is to quantify patterns
Data from: Rates of dinosaur limb evolution provide evidence for exceptional radiation in Mesozoic birds

- 摘要：
- within the avian crown group, long after the origin of flight. However, deep time patterns of bird evolution remain obscure because only limited fossil data hav
Data from: Pelvis morphology suggests that early Mesozoic birds were too heavy to contact incubate their eggs
- 负责人：
- DOI：
- doi:10.5061/dryad.k1v34cf
- 摘要：
- Numerous new fossils have driven an interest in reproduction of early birds but direct evidence remains elusive. No Mesozoic avian egg
Data from: Fossil evidence of the avian vocal organ from the Mesozoic
- 负责人：
- DOI：
- doi:10.5061/dryad.50n8j
- 摘要：
- the first remains, to our knowledge, of a fossil syrinx from the Mesozoic Era, which are preserved in three dimensions in a specimen from
Data from: The effect of weathering on bird bone survivorship in modern and fossil saline-alkaline lake environments
- 负责人：
- DOI：
- doi:10.5061/dryad.pd2p5
- 摘要：
- weathering can therefore obscure important taphonomic and paleoecological information. The weathering data collected here are then applied to a fossil bird
Data from: Probabilistic divergence time estimation without branch lengths: dating the origins of dinosaurs, avian flight and crown birds
- 负责人：
- DOI：
- doi:10.5061/dryad.p660m
- 摘要：
- the feasibility of probabilistic time-scaling further opens up divergence estimation to the rich histories of extinct biodiversity in the fossil record, eve
