ABSTRACT The Waterloo Farm lagerstätte in South Africa provides a uniquely well‐
preserved record of a Latest Devonian estuarine ecosystem. Ecological evidence from it is …

The discovery of Entelognathus revealed the presence of maxilla, premaxilla, and dentary,
supposedly diagnostic osteichthyan bones, in a Silurian placoderm. However, the …

Major groups of jawed vertebrates exhibit contrasting conditions of dermal plates and
scales. But the transition between these conditions remains unclear due to rare information …

A series of recent studies recovered consistent phylogenetic scenarios of jawed vertebrates,
such as the paraphyly of placoderms with respect to crown gnathostomes, and antiarchs as …

The Diplacanthiformes are a clade of acanthodian fishes which were widespread during the
Middle and early Late Devonian. They are best represented in the Middle Devonian, by …

Anatomical knowledge of early chondrichthyans and estimates of their phylogeny are
improving, but many taxa are still known only from microremains. The nearly cosmopolitan …

We resolve debate over the evolution of vertebrate hypermineralized tissues through
analyses of matrix protein-encoding secretory calcium-binding phosphoprotein (SCPP) …

Osteichthyans comprise two divisions, each containing over 32,000 living species [1]:
Sarcopterygii (lobe-finned fishes and tetrapods) and Actinopterygii (ray-finned fishes) …

ABSTRACT Doliodus problematicus (NBMG 10127), from the Lower Devonian of New
Brunswick, Canada (approx. 397–400 Mya) is the earliest sharklike jawed vertebrate …

Romer's Gap, the interval following the end‐Devonian extinction event, has been described
as a post‐extinction trough for vertebrates. It is a time roughly equivalent to the Tournaisian …
