Supporting Information for Pyenson et al. PeerJ (2025) on Al Maszhabiya bonebed from Qatar

(1 file) Spreadsheet of locality data, taphonomy, and body size data from the Al Maszhabiya bonebed: This spreadsheet contains several tabs with datasets that include locality data, taphonomic scording, body size data, and rib measurements (including those from modern sirenian museum specimens, for comparison). Global positioning system (GPS) coordinates of all localities can be requested from Qatar Museums: Al Maszhabiya - taphonomy and body size data - Aug 2025 - NO GPS.xlsx (1 file) NEXUS file for phylogenetic analysis: This Mesquite file including all specimens, but not coding for biogeographic regions. The trees were generated using implied weights of K=3, K = 9; K = 12: Pyenson et al-NoBio.nex (2 files) Final orthographic photogrammetry files for fossil dugongid localities: These high resolution images are orthographic aerial views of two localities of the Al Maszhabiya bonebed: FD 23-14 and FD 23-75: FD 23-14 - 5 pm 14 May 23(257 um per pix.jpg FD 23-75 - 430 pm 14 May 23(262 um per pix).jpg (3 folders) Al Maszhabiya bonebed localities image database: These three folders contain images for fossil dugongid-bearing localities of the Al Maszhabiya bonebed. They include: a) one set covering FD 23-001 to FD 230148; b) a second set covering JL localities, some of which are harmonized with FD 23 locality series; and c) validation of rib measurements from both FD 23 and JL localities: FD localities - photo database - FD 23-001 to FD 23-148.zip JL localities 2009 Al Maszhabiya images.zip FS 23 and JL localities Al Maszhabiya rib measurements.zip
