Variation and disparity within the inner ear and trigeminus of the Tenrecomorpha

How does the evolution of specialized sensory systems relate to adaptive radiation? Does adaptation to different ecological niches correlate significantly with changes in sensory anatomy? The afrotherian clade Tenrecomorpha, represented today by the African potamogalines and the Malagasy tenrecines, is of particular interest in this regard because of its extraordinary variety: its membership reportedly includes fossorial, arboreal, semiaquatic, and even echolocating taxa. To investigate their sensory ecology further, here we provide geometric morphometric analyses of inner ear endocasts (i.e., the bony labyrinth) of 24 tenrec species. We expand this data set with iodine-stained specimens of an additional 9 species, to provide information on cerebral and trigeminal organization. Although tenrecomorphs display cross-taxon differences in structures that may relate to sensory ecotype, our analyses distinguish signals of conflicting strength and direction within the tenrec ear. We found no s..., Skulls of 24 tenrecomorph species were scanned on the GE Phoenix Vtome x SMicroCT scanner in the AMNH Microscopy and Imaging Facility (MIF), at a target resolution between 18-56 μm. For all taxa, the left bony labyrinth of adult specimens was segmented. For 4 specimens where this structure was damaged or otherwise unsuitable for analysis, the right cochlea was segmented and mirrored prior to analysis. For rendering, specimens were reconstructed with the 3DSlicer software suite and semilandmarks placed using the SlicerMorph package. For fixed landmarks, landmarks were collected, translated from a template (Nesogale talazaci) using the ALPACA module, and corrected/resampled by hand where necessary. Cochlear and semicircular landmarks were placed and resampled manually for each specimen, and all landmarks were merged to form the final dataset., , # Variation and disparity within the inner ear and trigeminus of the Tenrecomorpha

This dataset contains the code and raw landmark data needed to recreate the analyses in this paper.
We have submitted the raw landmark data (including **Curved_Landmarks** and **Fixed_Landmarks**) models of of the inner ear bony labyrynth (**Inner_Ears**) in addition to the data files for running analyses: a trimmed phylognetic tree (**tenrec_pruned.tre**), categorical data (**Table_S1_Tenrec_Categories**) measurements from the trigeminal nerve (**Table S3 Traw_Trigeminal_Data**) and R code required to recreate the analyses in this paper (**Code_Resubmission_Final**)  

## Description of the data and file structure

Included are three folders:

**Curved_Landmarks**: This folder contains the unadjusted semilandmark curves for each specimen, saved as JSON files. The specimen name for each is located in the filename.

**Fixe...,
