Taxonomy
Baena antiqua was named by Lambe (1902). Its type specimen is NMC 1648, a carapace (the anterior lobe of the plastron and the anterior central portion of the carapace), and it is a 3D body fossil. Its type locality is below mouth of Berry Creek (NMC), which is in a Campanian terrestrial horizon in Canada.

It was recombined as Plesiobaena antiqua by Gaffney (1972), Bryant (1989), Brinkman (2003), Lyson and Joyce (2009), Perea et al. (2014), Joyce and Lyson (2015) and Smith et al. (2023).

Synonyms
  • Baena callosa was named by Hay (1905). Its type specimen is CM 330, a partial shell, and it is a 3D body fossil. Its type locality is Willow Creek (CM), which is in a Campanian/Campanian terrestrial horizon in the Judith River Formation of Montana.

    It was synonymized subjectively with Plesiobaena antiqua by Joyce and Lyson (2015).

Diagnosis
ReferenceDiagnosis
E. S. Gaffney 1972 (Baena callosa)It is seen that B hatcheri has, relatively to the width of the bridge, large anterior and posterior lobes; that B. marshi has both lobes small; and that B. callosa has the anterior lobe short and of moderate width, while the hinder lobe is broad at the base" (ibid., p. 182).
