Stratigraphic and paleogeographic distributions of Devonian crinoids from Spain with description of new taxa from the Iberian Chains
Abstract. A new Lower Devonian fauna from the Iberian Chains (NE Spain) is described. Specimens have been collected from the shaley intervals of the Mariposas Formation dated as early Emsian. These
First report of a Palaeozoic fenestrate bryozoan with an articulated growth habit
PurposeThe main goal of this paper is the description of the erect articulated growth habit for the first time within the Palaeozoic Order Fenestrata, and the interpretation of its occurrence within
Filling the Gondwanan gap: paleobiogeographic implications of new crinoids from the Castillejo and Fombuena formations (Middle and Upper Ordovician, Iberian Chains, Spain)
Abstract. A diverse crinoid fauna is described from the Upper Ordovician (Katian) Fombuena Formation from the eastern Iberian Chains of Spain. New crinoids include the diplobathrid camerates
Phylogeny, Diversification, and Extinction Selectivity in Camerate Crinoids
This chapter discusses the phylogenetic analysis of crinoids from the Middle and Upper Ordovician formations in Spain and the effects of ecology on morphologic rate heterogeneity and Hierarchical controls on extinction selectivity across the diplobathrid crinoid phylogeny.
Progress in echinoderm paleobiology
The echinoderm skeleton is rich in characters for rigorous analyses of disparity, functional morphology, and phylogeny, providing the means to tackle large-scale evolutionary questions and making echinoderms an ideal group for addressing fundamental questions about the history of life on Earth.


Equinodermos del cámbrico medio de las cadenas ibéricas y de la zona cantábrica (norte de España)
Se estudian los equinodermos del Cambrico medio procedentes de las Cadenas Ibericas y de la Zona Cantabrica. El muestreo de once localidades ha permitido reconocer cincuenta niveles fosiliferos con
Late Cambrian hard substrate communities from Montana/Wyoming: the oldest known hardground encrusters
Hardground surfaces from the Late Cambrian Snowy Range Formation in Montana/Wyoming are the oldest known non-reefal hard substrates exhibiting encrusting fossils. These surfaces range in age from
The oldest echinoderm faunas from Gondwana show that echinoderm body plan diversification was rapid.
The discovery of two new echinoderm faunas from the early part of the Cambrian of Morocco (West Gondwana) indicates that considerable diversification had already taken place by 510 Ma, and suggests that a rapid rate of morphological divergence took place during the initial stages of echinoderms evolution.
The role of abiotic factors in the Cambrian Substrate Revolution: A review from the benthic community replacements of West Gondwana
Abstract The Cambrian Substrate Revolution refers to a substantial and “rapid” change to the nature of marine sedimentary substrates in the early Cambrian and is widely interpreted as a

It is demonstrated that Cambrian echinoderms show surprising variability in the way their appendages are constructed, and that the appendages of at least some blastozoans arose as direct outgrowths of the body in much the same way as the arms of crinoids.
Middle Cambrian echinoderms from north Spain show echinoderms diversified earlier in Gondwana
New fossil discoveries in the middle Cambrian of Spain have considerably expanded our knowledge of the temporal and spatial distribution of some major clades of echinoderms including sucocystid
