Fossilized ontogenies: The contribution of placoderm ontogeny to our understanding of the evolution of early gnathostomes

, 2014
Placoderms, representing phylogenetically more inclusive jawed vertebrates and successive sister taxa to crown-group gnathostomes, are critical to our understanding of character evolution within the crown-group (chondrichthyans + osteichthyans ...

Unique diversity of acanthothoracid placoderms (basal jawed vertebrates) in the Early Devonian of the Prague Basin, Czech Republic: A new look at Radotina and Holopetalichthys.

PLoS ONE, 2017
The taxonomy of Early Devonian placoderm material from the Lochkovian and Pragian of the Prague basin, previously attributed to the genera Radotina and Holopetalichthys, is revised.

Ornamentation of dermal bones of Placodermi from the Lower Devonian of Morocco as a measure of biodiversity [PDF]

, 2017
Dermal bones are formed early during growth and thus constitute an important tool in studies of ontogenetic and evolutionary changes amongst early vertebrates.

The Evolution of the Zygomatic Bone From Agnatha to Tetrapoda

, 2016
Establishing the homology of the zygomatic or jugal bone and tracing its origin and early evolution represents a complex issue because of large morphological gaps between various groups of vertebrates.

Development of teeth and jaws in the earliest jawed vertebrates

, 2012
Teeth and jaws constitute a model of the evolutionary developmental biology concept of modularity and they have been considered the key innovations underpinning a classic example of adaptive radiation. However, their evolutionary origins are much debated.

Fossil Musculature of the Most Primitive Jawed Vertebrates

, 2013
The transition from jawless to jawed vertebrates (gnathostomes) resulted in the reconfiguration of the muscles and skeleton of the head, including the creation of a separate shoulder girdle with distinct neck muscles.
