Genomic insights into the secondary aquatic transition of penguins [PDF]
Nature Communications, 2022 This study examines the tempo and drivers of penguin diversification by combining genomes from all extant and recently extinct penguin lineages, stratigraphic data from fossil penguins and morphological and biogeographic data from all extant and extinct ...

Estimating the Age of Poorly Dated Fossil Specimens and Deposits Using a Total-Evidence Approach and the Fossilized Birth-Death Process. [PDF]
Syst Biol, 2023 Bayesian total-evidence approaches under the fossilized birth-death model enable biologists to combine fossil and extant data while accounting for uncertainty in the ages of fossil specimens, in an integrative phylogenetic analysis.

A new tiny fossil penguin from the Late Oligocene of New Zealand and the morphofunctional transition of the penguin wing. [PDF]
J R Soc N ZThe Late Oligocene is a period of high penguin diversity, following major changes in the marine environment at the Eocene/Oligocene boundary and prior to the emergence of crown penguins in the Miocene.

Fossil and modern penguin tarsometatarsi: cavities, vascularity, and resilience. [PDF]
Integr ZoolPenguin tarsometatarsi are shortened and flattened, and studies devoted to the internal characteristics of these composite bones are very limited. Therefore, we present here a comprehensive, x‐ray‐microscopy‐based analysis based on tarsometatarsi of ...

Bayesian total evidence dating reveals the recent crown radiation of penguins [PDF]
Systematic Biology, 2016 The total-evidence approach to divergence-time dating uses molecular and morphological data from extant and fossil species to infer phylogenetic relationships, species divergence times, and macroevolutionary parameters in a single coherent framework ...

From fossils to conservation: an overview of Antarctic and sub-Antarctic penguins [PDF]
PolarforschungPenguins are among the most distinctive birds of the Antarctic and sub-Antarctic, and their story spans from extinct “giant” fossil species to the penguins that breed today.

The hearing capabilities of the Dromornithidae (Aves), with inferences on acoustic communication and ecology. [PDF]
J AnatThe preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in

An integrative insight into the synsacral canal of fossil and extant Antarctic penguins.
Integrative Zoology, 2022 The lumbosacral-canal system in birds most likely operates as a sense organ involved in the control of balanced walking and perching, but our knowledge of it is superficial.

At the root of the early penguin neck: a study of the only two cervicodorsal spines recovered from the Eocene of Antarctica [PDF]
Polar Research, 2014 The spinal column of early Antarctic penguins is poorly known, mainly due to the scarcity of articulated vertebrae in the fossil record. One of the most interesting segments of this part of the skeleton is the transitional series located at the root of ...

New mammalian and avian records from the late Eocene La Meseta and Submeseta formations of Seymour Island, Antarctica [PDF]
PeerJ, 2020 The middle–late Eocene of Antarctica was characterized by dramatic change as the continent became isolated from the other southern landmasses and the Antarctic Circumpolar Current formed.
