Fig. 6 in A Possible Heptaxodontine and Other Caviidan Rodents from the Quaternary of Jamaica

Fig. 6. Right proximal femora of heptaxodontine Amblyrhiza inundata (Anguilla/St. Martin): AMNHP 11847 (''small'' morph) in (A) caudal aspect; AMNHP 11843/O (''large'' morph) in (B) caudal, (C) caudomedial, and (D) craniolateral aspects; and AMNHP 11843/N (''large'' morph) in (E) lateral aspect. (Photographs after Biknevicius et al., 1993; drawings after Cope, 1883.) Similarities in morphology suggest that Sheep Pen femur (fig. 5A–C) may belong to a megafaunal caviidan, although beyond general resemblance there is nothing that specifically indicates a relationship to Amblyrhiza. (For discussion of size variability in Amblyrhiza, see Biknevicius et al., 1993). Key: hd, head; lt, lesser trochanter; tf, trochanteric fossa; tgt, ''towered'' greater trochanter.
