One of the oldest notoungulate skeletons with associated craniodental and postcranial elements is described. The dataset includes body mass estimates, bone histology, and phylogenetic analysis for the specimen from the middle Eocene of Patagonia, Argentina. D Carrillo from the University of Zurich authored the research project.
Use Cases
- Estimating body mass evolution in early notoungulates based on skeletal element data.
- Analyzing phylogenetic relationships among placental mammals based on combined DNA, collagen, and morphology matrices.
- Studying skeletal maturity and bone histology in Eocene mammalian fossils.
- Comparing anatomical features like scapulae and humerii across specimens of Thomashuxleya externa.
Strengths
- Includes body mass estimates of 84 ± 24.2 kg for the specimen.
- Combines craniodental, postcranial, histological, and phylogenetic data for a single specimen.
- Specimen is from a well-defined geological context: the middle Eocene (Vacan subage, Casamayoran SALMA) of Patagonia, Argentina.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
