A revised phylogenetic framework for ornithischian dinosaurs, based on an exhaustive compilation and critical re-evaluation of published osteological character data. The work includes recently described basal ornithischians, marginocephalians, and ornithopods. Author Paul-Émile Dieudonné presents this analysis, which reconfigures basal cerapodan relationships and discusses ornithopod phylogeny.
Use Cases
- Testing phylogenetic hypotheses for Cerapoda based on osteological character scoring.
- Analyzing the evolutionary relationships of basal Iguanodontia, including Tenontosaurus.
- Studying the paraphyletic nature of 'heterodontosaurids' and their placement within Marginocephalia.
Strengths
- Analysis is based on an exhaustive compilation of previously published phylogenetic data.
- Includes a critical re-evaluation and in-depth checking of character scoring to fix accumulated mistakes.
- Incorporates recently described taxa such as basal ornithischians, marginocephalians, and ornithopods.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
