The analysis of the hyoid apparatus of fossil xenarthrans provides insight on the form of the tongue and its function in food intake and intraoral processing. The hyoid apparatus of xenarthrans is notable for fusion among its elements. The presence of a V‐bone, a complex consisting of fused basihyal and thyrohyal bones, is a consistent and probably synapomorphic feature of xenarthrans. Fusion of other elements is variable in fossil xenarthrans. Most fossil sloths retain independent elements, as… 

The evolution of hyoid apparatus in Xenarthra (Mammalia: Eutheria)

The morphology of the hyoid apparatus in xenarthrans is compared, describing its general morphology and variation in each major clade and scoring these variations as phylogenetic characters, which were submitted to ancestral states reconstructions.

New Jurassic mammaliaform sheds light on early evolution of mammal-like hyoid bones

A Jurassic fossil shows that early premammalian ancestors possessed hyoids similar to those seen in mammals today, and a new Jurassic docodontan mammaliaform found in China that is preserved with the hyoid bones is reported.

Description of the stylohyal bone of a giant sloth (Lestodon armatus)

A right stylohyal found in the late Pleistocene megafaunal bonebed of the Arroyo del Vizcaino site, Uruguay is described as two perfectly matched pieces that were within a few centimeters of each other.

A new record of Lestodon armatus Gervais 1855 (Xenarthra, Mylodontidae) from the Quaternary of southern Brazil and remarks on its postcranial anatomy

A new specimen assigned to L. armatus is reported from a Quaternary deposit in Caçapava do Sul, southern Brazil, composed of cranial fragments, vertebrae, articulated hind limb and pes, as well as other post-cranial elements.

Tracing the Paleobiology of Paedotherium and Tremacyllus (Pachyrukhinae, Notoungulata), the Latest Sciuromorph South American Native Ungulates – Part II: Orbital, Auditory, and Occipito-Cervical Regions

The integrative analysis proposed here and in the accompanying contribution aims to shed light on convergences with extant models, paleobiology, niche partitioning, and external appearance of the latest rodent-like ungulates.

Cranial Anatomy and Paleoneurology of the Extinct Sloth Catonyx tarijensis (Xenarthra, Mylodontidae) From the Late Pleistocene of Oruro, Southwestern Bolivia

The combined information from the external and internal anatomy suggests reduced lingual protrusion in Catonyx tarijensis, or at least a consistently more limited protrusion of the tongue in comparison with other mylodontid sloths such as Glossotherium robustum.

Digital Cranial Endocasts of the Extinct Sloth Glossotherium robustum (Xenarthra, Mylodontidae) from the Late Pleistocene of Argentina: Description and Comparison with the Extant Sloths

This study, which represents the first exhaustive analysis of digital endocasts of a fossil sloth, reveals the importance of the application of new methodologies, such as CT scans, for elucidating the evolutionary history of this peculiar mammalian clade.

The howl of Rancho La Brea: Comparative anatomy of modern and fossil canid hyoid bones

This study compares fossilized hyoid elements from Canis dirus and Canis latrans to samples from modern large congeners, namely: Canis lupus (the gray wolf), Canis rufus ( the red wolf), and modern C. latrans.

Anatomy description of cervical region and hyoid apparatus in living giant anteaters Myrmecophaga tridactyla Linnaeus, 1758

The bone contours in the hyoid apparatus of the giant anteater is described by means of radiographic and tomographic images and the presence of air in the oropharynx enabled the assessment of soft tissue structures in this region, such as the epiglottis and the soft palate.

The combination of tooth features that characterize xenarthrans might be seen as the key innovation for the ecologic diversity developed at least since the Oligocene, breaking the mold of the tribosphenic condition that constrained the evolution of the other major clades of mammals.

The proposed model of hyoid function predicts that this arrangement aids an inverted sloth in opening the mouth fully against gravity while permitting the hyoid to move anteriorly during tongue extension independent of the sternomandibularis.

Skull Shape, Masticatory Apparatus, and Diet of Vassallia and Holmesina (Mammalia: Xenarthra: Pampatheriidae): When Anatomy Constrains Destiny

The various skeletal and dental features analyzed suggest that the masticatory apparatus of the pampatheres was more powerful and efficient in transverse chewing than in dasypodids and that they were primarily grazers consuming mainly coarse vegetation.

Morphology, evolution and function of feeding in the giant anteater ( Myrmecophaga tridactyla )

Mandibular rotation in lieu of depression and elevation simplifies jaw movements made by a smaller uniquely modified muscle mass over shorter distances, therefore increasing the speed with which anteaters can ingest food, and complements the extremely rapid tongue protrusion–retraction cycle.
