Potential for powered flight neared by most close avialan relatives but few crossed its thresholds

Rui Pei, Michael Pittman, Pablo A. Goloboff, T. Alexander Dececchi, Michael B. Habib, Thomas G. Kaye, Hans C.E. Larsson, Mark A. Norell, Stephen L. Brusatte & Xing Xu
This dataset is the Supplementary Materials of the Pei, Pittman et al. (2020) study 'Potential for powered flight neared by most close avialan relatives but few crossed its thresholds' in Current Biology (https://doi.org/10.1016/j.cub.2020.06.105). In this study, a revised phylogeny of coelurosaurian theropod dinosaurs was used to reconstruct their potential for powered flight. It found that powered flight potential evolved at least three times (once in birds and twice in dromaeosaurids) and that many ancestors of...

A new species of Eogruidae (Aves: Gruiformes) from the Miocene of the Linxia Basin, Gansu, China: Evolutionary and climatic implications

Grace Musser, Zhiheng Li & Julia A Clarke
Despite having one of the most robust fossil records within core-gruiform birds (rails, cranes, and allies), the biogeographic history of Gruidae (cranes) and key drivers of diversification within this group remain largely unknown. The Eogruidae of Eurasia represent some of the earliest known crane-like fossils. Here, we present description of a new species represented by a well-preserved specimen of a foot from the late Miocene (7–6.5 mya) Liushu Formation of Linxia Basin, Gansu, China. It...

Data from: Using parsimony-guided tree proposals to accelerate convergence in Bayesian phylogenetic inference

Chi Zhang, John Huelsenbeck & Fredrik Ronquist
Sampling across tree space is one of the major challenges in Bayesian phylogenetic inference using Markov chain Monte Carlo (MCMC) algorithms. Standard MCMC tree moves consider small random perturbations of the topology, and select from candidate trees at random or based on the distance between the old and new topologies. MCMC algorithms using such moves tend to get trapped in tree space, making them slow in finding the globally most probable trees (known as `convergence')...

Early Silurian chondrichthyans from the Tarim Basin (Xinjiang, China)

Plamen Andreev, Wenjin Zhao, Nian-Zhong Wang, Moya Smith, Li Qiang, Xindong Cui, Min Zhu & Ivan Sansom
The Sinacanthida ordo nov. and Mongolepidida are spine- and scale-based taxa whose remains encompass some of the earliest reported fossils of chondrichthyan fish. Investigation of fragmentary material from the Early Silurian Tataertag and Ymogantau Formations of the Tarim Basin (Xinjiang Uygur Autonomous Region, China) has revealed a diverse mongolepidid and sinacanthid fauna dominated by mongolepids and sinacanthids in association with abundant dermoskeletal elements of the endemic ‘armoured’ agnathans known as galeaspids. Micro-computed tomography, scanning electron...
