The phylogeny and classification of post-Palaeozoic echinoids
TLDR
The relationships of post-Palaeozoic echinoids at family level are established through phylogenetic analysis of 169 taxa and 306 skeletal characters (excluding pedicellariae) and a well-resolved phylogenetic hypothesis was obtained and is used as the basis for a formal classification.
Systematics and the Fossil Record: Documenting Evolutionary Patterns
  • A. Smith

  • 14 June 1994
TLDR
This paper presents a meta-anatomical reconstruction of the distribution of phylogenetic trees in the fossil record from Carboniferous strata using a probabilistic approach and shows clear trends in tree-building and phylogenetic analysis.
THE SHAPE OF THE PHANEROZOIC MARINE PALAEODIVERSITY CURVE: HOW MUCH CAN BE PREDICTED FROM THE SEDIMENTARY ROCK RECORD OF WESTERN EUROPE?
Abstract:  Palaeodiversity curves are constructed from counts of fossils collected at outcrop and thus potentially biased by variation in the rock record, specifically by the amount of sedimentary
Systematics and the Fossil Record
TLDR
The real purpose of Smith's book is not to provide a tutorial for cookbook cladistics, but instead to present an outline of the potential implications of phylogenetic studies on previous paleobiological studies and what paleontologists can do within a phylogenetic estimate.
Deciphering deuterostome phylogeny: molecular, morphological and palaeontological perspectives

  • 27 April 2008
TLDR
Molecular phylogenies, larval morphology and the adult heart/kidney complex all support echinoderms and hemichordates as a sister grouping (Ambulacraria), andGene network data suggest that the ancestral deuterostome ancestor had an anterior–posterior body axis specified by Hox and Wnt genes, and was bilaterally symmetrical with left–right asymmetry determined by expression of nodal.
Sea-level change and rock-record bias in the Cretaceous: a problem for extinction and biodiversity studies
Abstract The association between mass extinction in the marine realm and eustatic sea-level change in the Mesozoic is well documented, but perplexing, because it seems implausible that sea-level
Tectonics from fossils? Analysis of reef-coral and sea-urchin distributions from late Cretaceous to Recent, using a new method

Abstract Biogeographical distribution is seen as a product of small- and large-scale factors, of which only the latter are important in palaeogeographical reconstruction. We review here previous
Testing the molecular clock: molecular and paleontological estimates of divergence times in the Echinoidea (Echinodermata).
TLDR
The level of agreement reached between different data and methodological approaches leads us to believe that careful application of likelihood and Bayesian methods to molecular data provides realistic divergence time estimates in the majority of cases, thus providing a remarkably well-calibrated phylogeny of a character-rich clade of ubiquitous marine benthic invertebrates.
Ophiuroid phylogeny and higher taxonomy: morphological, molecular and palaeontological perspectives
TLDR
A cladistic analysis of the class Ophiuroidea at subfamily level is presented based on a morphological data base of 43 characters, which identifies Ophiocanopidae as sister group to other extant ophiuroids, which themselves fall into two major groups.
The interrelationships of the echinoderm classes: morphological and molecular evidence
TLDR
This work has reviewed all available morphological and molecular data, added new data and reanalysed independent data sets individually and in combination, in order to resolve echinoderm class relationships and picks out (outgroup(C(A(O(E,H))))) and (out group(C((A,O),( E,H)))) as the two most plausible phylogenetic hypotheses.
