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).

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| 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). | |
