Resumen

Medidas realizadas con un calibre sobre cráneos y mandíbulas de roedores sigmodontinos pertenecientes a distintos ensambles del centro-este de Argentina.

Métodos

The following measurements were performed on the cranium: braincase breadth (BCB): widest breadth of the braincase, taken between the temporal bones; breadth across the masseteric tubercle (BAMT): ventral breadth of the rostrum between the lingual edges of the masseteric tubercles, at the base of the zygomatic plates; breadth of the bony palate at the first molar (BBPM1): breadth of the bony palate measured at the medium point of the second cusp of M1, on the external edges of the alveoli; breadth of the bony palate at the third molar (BBPM3): breadth of the bony palate measured at the medium point of M3, on the external edges of the alveoli; condyle-incisive length (CI): length of the cranium measured from the anterior end of the incisor alveolus to the posterior end of the occipital condyle; infraorbital foramina height (IFH): dorsoventral width of the infraorbital foramen, measured between the ventral edge of the superior root of the zygomatic arch to the rostro-ventral edge of the zygomatic plate; incisive foramina length (IFL): length of the incisive foramen, measured from its anterior to its posterior end; least intraorbital breadth (LIOB): dorsal breadth of the intraorbital region, considering the narrowest distance between the frontal bones; orbital interior length (OIL): length of the orbital region, measured from the posterior end of the zygomatic plate to the anterior edge of the glenoid cavity; palatal bridge (PB): length of the bony palate, measured from the posterior end of the incisive foramina to the anterior end of the mesopterygoid pit; post-palatal length (PPL): distance between the bony palate and the foramen magnum, measured from the anterior edge of the mesopterygoid pit to the anterior edge of the foramen magnum; rostrum length (RL): length of the rostrum, measured from the posterior end of the zygomatic notch to the anterior end of the nasal bone; upper diastema length (UDL): length of the upper diastema, measured from the posterior end of the incisor alveolus to the anterior end of the first molar alveolus; upper molar row length (UMRL): length of the upper molar row, considered from the anterior end of the first molar alveolus to the posterior end of the last molar alveolus; zygomatic breadth (ZB): major breadth between the exterior edges of zygomatic arches; zygomatic plate breadth (ZPB): breadth of the zygomatic plate on its medium portion. The following measurements were performed on the mandible: articular condyle breadth (ACB): breadth of the articular condyle measured on its broader part, from the labial to the lingual side; coronoid height (CH): height of the coronoid process, measured from the retromolar pit, on the caudal end of the third molar, to the anterior end of the coronoid process; lower diastema length (LDL): length of the lower diastema, from the posterior end of the incisor alveolus to the anterior end of the first molar alveolus, measured on the labial side of the mandible; lower molar row length (LMRL): length of the lower molar row, considered from the anterior end of the first molar alveolus to the posterior end of the last molar alveolus; mandibular angle breadth (MAB): from the retromolar pit, on the caudal end of the third molar, to the posterior end of the angular process; mandibular angle height (MAH): from the superior end of the articular condyle to the inferior end of the mandibular angle; mandibular ramus height (MRH): height of the mandibular ramus measured from the labial edge of the first molar alveolus, underneath the second cusp, vertically to the lower edge of the mandible; semilunar height (SH): height of the semilunar notch, considered from the distal end of the angular process to the inferior end of the condylar process; sigmoid notch (SN): length of the sigmoid notch, measured from the posterior end of the coronoid process to the anterior end of the condylar process measured on the lingual side of the mandible; symphysis length (SL): length of the mandibular symphysis, considered from the anterior end of the incisor alveolus to the inferior end of the mandibular symphysis, measured on the lingual side of the mandible.
