A tractable aggregation-diffusion model with a distance-dependent attraction to the midline produces compactly supported cell-density patterns with central or multiple peaks, offered as a mechanism for turtle keel formation.
Keel formation is observed during embryonic development, a stage in which the ribs grow outward from the midline (Okada et al., 2011; Paredes et al., 2020; Akashi et al., 2022)
