Craniodental morphology and phylogeny of marsupials

Abstract: The current literature on marsupial phylogenetics includes numerous studies based on analyses of morphological data with relatively limited sampling of Recent and fossil taxa, and many studies based on analyses of molecular data that include a dense sampling of Recent taxa, but relatively few that combine both data types. Another dichotomy in the marsupial phylogenetic literature is between studies that focus on New World taxa, others that focus on Sahulian taxa. To date, there has been no attempt to assess th… Show more

“…(2010), Sharp (2016), Sharp & Rich (2016), Trusler & Sharp (2016) and Beck et al . (2022). Such parietal sinuses are present in a range of extinct large‐bodied Vombatiformes, including Nimbadon , Neohelos , Silvabestius , Thylacoleo , Palorchestes , Kolopsis and Diprotodon .…”

“…This last sinus is incomplete but is the largest preserved: 42 mm in length and 50 mm in height; it probably represents the dorsal part of the posterior epitympanic sinus that is present in other vombatids and most other diprotodontians (Beck et al . 2022).…”

“…The presence of a well-developed posterior cingulid in MUSM 4018 is a striking feature, since this structure was until recently considered to be absent in all didelphids, and also in paucituberculatans and microbiotheriids (Beck et al, 2021). A posterior cingulid is now described for two didelphids, as well as in basal ameridelphians (Beck et al, 2021) and caenolestid paucituberculatans (Abello et al, 2021).…”

“…The following characteristics allowed the assignment of this material to Didelphidae, according to Voss and Jansa (2009): tribosphenic lower molars, with a developed anterior cingulid (notched for the hypoconulid of the preceding tooth), as well as notched paracristids. However, it is important to mention that some authors consider that there are no synapomorphies on the lower molars that undoubtedly characterize the family Didelphidae (Beck et al, 2021). Compared to other Miocene didelphids, the TAR-31 specimen is much smaller than Didelphis solimoensis Cozzuol, Goin, de los Reyes, and Ranzi, 2006 from Acre (Cozzuol et al, 2006), besides having less developed anterior cingulid and more compressed entoconid.…”
