Estimación de masa corporal de proterotéridos del Cuaternario (Mammalia, Litopterna) y descripción de un nuevo ejemplar de Neolicaphrium recens Frenguelli, 1921

Abstract: Body mass estimation of Quaternary proterotheriids (Mammalia, Litopterna) and description of a new specimen of Neolicaphrium recens Frenguelli, 1921. A body mass estimation for Quaternary specimens of the family Proterotheriidae was performed using predictive regression equations for extant ungulates. A body mass of 20-40 kg for Neolicaphrium recens and of <70 kg for Uruguayodon alius are determined based on the analysis of dental, mandibular, and postcranial dimensions including lengths, areas, and volumes.

“…This trend included, on the one hand, increased maximum body mass with respect to the Miocene toxodontians and macrauchenians (110 kg Adinotherium and 640 kg Nesodon, and about 140 kg Theosodon respectively; see Cassini et al, 2012). On the other hand, the formerly abundant and diverse typotherians and proterotheriids experienced a remarkable reduction in diversity, being represented in the Pleistocene mainly by the 1.9 kg Paedotherium and 20-40 kg Neolicaphrium, respectively (see Elissamburu, 2004;Ghizzoni et al, 2020).…”

“…Estos sedimentos, además de incluir fósiles de maderas, diversos taxones de moluscos en su mayoría dulceacuícolas, coprolitos y un peculiar icnofósil interpretado como trazas de estivación de lombrices (Verde et al, 2007), han proporcionado registros de vertebrados, en particular aves y predominantemente mamíferos. Estos mamíferos están representados al momento por unas 25 familias incluyendo unas 55 especies, algunas vivientes hoy en día en otras áreas del continente, mostrando un amplio espectro de masas corporales (desde pequeños roedores a megafauna) y adaptaciones tróficas y ambientales, sustentado en parte por estudios en algunos taxones de microdesgaste dentario e isótopos estables (Prevosti et al, 2009;Gasparini et al, 2013;Ghizzoni, 2014;Manzuetti et al, 2018bManzuetti et al, , 2020aManzuetti et al, , 2020bMorosi y Ubilla, 2018Corona et al, 2019b;Ghizzoni et al, 2020). Varios taxones de aves han sido registrados para estos sedimentos, tales como el cauquén Cloephaga picta (Gmelin, 1789), la seriema Cariama cristata (Linnaeus, 1766), horneros identificados como cf.…”
