title: Widespread convergence towards functional optimisation in the lower jaws of crocodile-line archosaurs

description: Extant crocodilian jaws are subject to functional demands induced by
 feeding and hydrodynamics. However, the morphological and ecological
 diversity of extinct crocodile-line archosaurs is far greater than living
 crocodilians, featuring repeated convergence towards disparate ecologies
 including armoured herbivores, terrestrial macropredators, and fully
 marine forms. Crocodile-line archosaurs therefore present a fascinating
 case study for morphological and functional divergence and convergence
 within a clade across a wide range of ecological scenarios. Here we build
 performance landscapes of two-dimensional theoretical jaw shapes to
 investigate the influence of strength, speed and hydrodynamics in the
 morphological evolution of crocodile-line archosaur jaws, and test whether
 ecologically convergent lineages evolved similarly optimal jaw function.
 Most of the 243 sampled jaw morphologies occupy optimised regions of
 theoretical morphospace for either rotational efficiency, resistance to
 Von Mises stress, hydrodynamic efficiency or a trade-off between multiple
 functions, though some seemingly viable shapes remain unrealised. Jaw
 speed is optimised only in a narrow region of morphospace whereas many
 shapes possess optimal jaw strength, which may act as a minimum boundary
 rather than a strong driver for most taxa. Functional convergence is
 common, with repeated evolution of shapes linked to specialised ecological
 roles including gracile jawed piscivores and more robust jawed herbivores.

 of crocodile-line archosaurs
 [https://doi.org/10.5061/dryad.dbrv15f6n](https://doi.org/10.5061/dryad.dbrv15f6n) The following dataset contains all raw data and secondary files needed to repeat the study linked above. Lateral jaw images of crurotarsans contained within were used to create a morphospace of theoretical 2D lateral jaw images that can were then subjected to functional testing. The resulting functional landscapes (also contained herein) can be used to assess the importance of function on crurotarsan jaw evolution. The dataset also contains files needed to carry out other analyses presented in the manuscript including the phylogenetic tree and convergence metrics. ## Description of the data and file structure 1\.
