Constructing a multiple‐part morphospace using a multiblock method
Popular current methods for quantifying variation in biological shape are well‐suited to analyses of isolated parts (e.g. the same bone from the skeletons of many individuals).

Morphometric patterns in Recent and fossil penguins (Aves, Sphenisciformes) [PDF]
A total of 622 skin specimens, 527 skeletons, and myological data compiled by Schreiweis (1972) were used to investigate morphometric patterns within and among the 18 Recent species of Spheniscidae, and to compare the family with a fighted species, the common diving‐petrel (Pelecanoides urinator), considered by some authorities to be similar to the ...

Eocene penguin fossils as archives of Antarctic weathering and climate change: insights from micro-X-ray fluorescence elemental mapping [PDF]
One of the richest known fossil records of penguins occurs in the Eocene La Meseta and Submeseta formations on Seymour Island, Antarctic Peninsula.

Abstract We present the first detailed description of Perudyptes devriesi, a basal penguin from the middle Eocene (~42 Ma) Paracas Formation of Peru, and a new analysis of all published extinct penguin species as well as controversial fragmentary specimens.

The earliest fossil record of a medium-sized penguin
The earliest fossil record of a medium-sized penguinThe fossil record of Antarctic Sphenisciformes dates as early as the late Palaeocene Cross Valley Formation, Seymour Island, Antarctic Peninsula. However, the best known Antarctic locality for early penguin remains (mainly isolated bones) is the Eocene La Meseta Formation that outcrops in the ...
