MicroCT scan of the skull of a platypus (Ornithorhynchus anatinus). Dataset to Grunstra et al. (2024) "Convergent evolution in Afrotheria and non-afrotherians demonstrates high evolvability of the mammalian inner ear"
MicroCT scan of the skull of a platypus (Ornithorhynchus anatinus). This dataset was part of a study on the evolution of the inner ear.
