Apalone lima

Reptilia - Testudines - Trionychidae

Taxonomy
Trionyx lima was named by Cope (1869). Its type specimen is AMNH 1167, an osteoderm (fragment of the distal end of a costal plate), and it is a 3D body fossil. Its type locality is Shiloh Marl, which is in a Burdigalian marginal marine marl in the Kirkwood Formation of New Jersey.

It was recombined as Amyda lima by Hay (1908), Hay (1930); it was considered a nomen dubium by Vitek and Joyce (2015); it was recombined as Apalone lima by Weems (2023).

Diagnosis
ReferenceDiagnosis
R. E. Weems 2023Carapace consists of thickened, flat costal elements with rounded distal edges. Dorsal surface is sculptured with rather high and narrow ridges running across the bone, separated by grooves that are somewhat wider than the ridges. Summits of the ridges are uneven. Connecting ridges are rare, but occasionally, a ridge divides or abruptly ends. Proximally, the ridges are somewhat irregular in their course; distally, they are narrow and much interrupted. Sulcal grooves are absent on the external surface of both the carapace and plastron.
