We consider the autopod as consisting of 3 segments, divided according to the following jointly-exhaustive mutually-disjoint part-hierarchy, listed distal to proximal

• skeleton of autopod (aka 'autopod')
  • skeleton of acropodium (aka 'acropodium')
  • metapodium skeleton (aka 'metapodium')
  • mesopodium skeleton (aka 'mesopodium')

Note that in this document and in the ontology we currently use the unambiguous skeletal-prefixed terms, and phenoscape-preferred terms in parentheses.

Hoever, it is also possible to first group the acropodium and metapodium - confusingly, this is sometimes called the acropodium (e.g. Wagner and Chin 2001). We accomodate this group, and introduce a new label 'digitopodium' (Ibrahim and Sereno) to group the proximal-most two elements

This gives us a second hierarchy (also part-wise JEPD):

• skeleton of autopod (aka 'autopod')
  • skeleton of digitopodium (aka 'digitopodium', 'acropodium (Wagner)')
    • skeleton of acropodium (aka 'acropodium')
    • metapodium skeleton (aka 'metapodium')
  • mesopodium skeleton (aka 'mesopodium')

This second hierarchy is consistent with the first, but includes an additional mereological sum for grouping purposes
