Occurs as single trails or network of randomly overlapping trails.</p><p>Material.—UFRGS-PV-1581- T #2, #5 (Fig. 6C), #8, #19, and #23 (Fig. 4B) present single trails. UFRGS-PV-1581- T #3 (Fig. 4A) and UFRGS-PV-1581- T #18 present two trails without overlapping. UFRGS-PV-1581- T #1 presents two overlapping trails and UFRGS-PV-1581- T #14 (Fig. 5A, B, E) presents three trails without overlapping. All of these bone fragments are referred to Hyperodapedon mariensis from Buriol Site, São João do Polêsine municipality, Rio Grande do Sul State, Brazil; Base of the Candelária Sequence (vertebrate remains associated to the lower subunit of the Hyperodapedon AZ), SMS, Paraná Basin; middle Carnian (lower Upper Triassic).</p><p>Description.—All 14 trails formed by successive mainly arcuate and apparently paired grooves on the bone surface (Figs. 4, 5A, B, E, 6C). In some cases, the grooves overlap, forming long arcuate grooves or crossing each other. Most of the trails present some degree of meandering. Trail length is 1.1–21.5 mm and the width is 0.1–4.4 mm.</p><p>Remarks.—The grooves that compose the trails are not always arcuate, with some trails also presenting straight grooves. Osteocallis leonardii (Collareta et al. 2023) presents both straight and arcuate grooves as well, but in opposition to the materials referred herein to O. mandibulus, the grooves are predominantly straight. In some of the trails it is difficult to ascertain if the grooves are indeed paired, especially when their overlapping results in long arcuate grooves. This makes the precise measurement of individual grooves nearly impossible. UFRGS-PV-1581- T #14 was found covered by a thin layer of iron oxide that served as a natural cast, allowing for the observation of the traces in a positive relief (Fig. 5A, B). Trails on UFRGS-PV-1581- T #5, #11, #14, and #23 are associated to clusters of grooves (Figs. 4B, D, 5A, B, 6C). In UFRGS-PV-1581- T #14 a cluster is overlapping one of the trails. The only association of trails with other borings occurs in UFRGS-PV-1581- T #3 (Fig. 4A 1).</p></div>	https://treatment.plazi.org/id/A253B73DFFFB4946593CFC8BFAFDF810	Public Domain	No known copyright restrictions apply.

Grooves are randomly orientated, often overlapping other grooves which are either perpendicular or parallel to one another. The intensity of the grooves culminates in an irregular furrow-like morphology for the trail.</p><p>Material.—UFRGS-PV-1581- T #12 (Fig. 4C), a bone fragment referred to Hyperodapedon mariensis from Buriol Site, São João do Polêsine municipality, Rio Grande do Sul State, Brazil; Base of the Candelária Sequence (vertebrate remains associated to the lower subunit of the Hyperodapedon AZ), SMS, Paraná Basin; middle Carnian (lower Upper Triassic).</p><p>Description.—Two overlapping, moderately deep trails formed by randomly oriented, overlapping grooves culminating in a furrow-like morphology. Isolated grooves outside of the furrow appear to be arcuate, but the intense overlapping prevents the precise observation of groove morphology. The length of the trails ranges from 8.37–14.38 mm and the width ranges from 0.33–1.47 mm.</p><p>Remarks.—Both trails described here are considerably narrower than the holotype of O. infestans (which came from the Exaeretodon sub-AZ of the Hyperodapedon AZ) and the grooves are not as thick. As in the holotype, some areas outside of the furrow present isolated grooves. The furrow-like morphology is readily distinguishable from what is seen in O. mandibulus (Fig. 4C).</p></div>	https://treatment.plazi.org/id/A253B73DFFF449485A00FF5EFE26FBEE	Public Domain	No known copyright restrictions apply.

Trail length is 3.29 mm and the width ranges from 0.25–1.48 mm.</p><p>Remarks.—The preservation of the trail prevents its ichnospecific classification, because it is not possible to ensure that the grooves are mainly arcuate and paired. The grooves do not appear to be organized in parallel rows and regularly spaced as seen in Osteocallis leonardii . The trail is closely associated with an irregular cluster of randomly oriented grooves (Fig. 4D).</p></div>	https://treatment.plazi.org/id/A253B73DFFF449485A00FBAFFEDAF94E	Public Domain	No known copyright restrictions apply.
