While at Rancho La Brea (RLB) the paleobiology of S. fatalis is analogous to African lions in terms of carcass utilization, far less is known about S. fatalis outside of southern California. Further, Smilodon gracilis specimens are rare and less studied throughout most of its former range. This study expands our understanding of Smilodon's dietary ecology in North America by using dental microwear texture analysis (DMTA) to quantify carcass utilization and feeding behavior via complexity (Asfc) and anisotropy (epLsar) in populations of S. gracilis and S. fatalis from Florida, USA. Results reveal that S. fatalis populations from Florida and RLB have indistinguishable diets across climatically disparate regions during the Pleistocene. Additionally, S. fatalis and S. gracilis in Florida appear indistinguishable based on dental microwear textures, suggesting both species exhibited a generalist feeding strategy despite their temporal and morphological differences. Lastly, microwear in S. gracilis demonstrates a shift away from a tougher and potentially harder diet (epLsar and Asfc) during the glacial Inglis 1A site, as compared to the interglacial Leisey Shell Pit 1A site-similar to previously documented dietary shifts in glacial and interglacial populations of S. fatalis at RLB. Collectively, our findings are consistent with the hypothesis that the dietary behavior of S. fatalis and S. gracilis was generally consistent across space and time, with more subtle dietary differences occurring during glacial versus interglacial periods.</p>","PeriodicalId":50965,"journal":{"name":"Anatomical Record-Advances in Integrative Anatomy and Evolutionary Biology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143781890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With a focus on elements of the chondrocranium at the tissue level, the papers in this issue emphasize key characteristics of hyaline cartilage to skull morphogenesis. Based on matrix properties and cellular capabilities, cartilage is the ideal skeletal tissue for directional growth, but it also has multiple possible fates beyond its well-established importance as the source for endochondral components of the skull. In this issue, we have provided a greater focus on other fates, including persistence as cartilage or dictating the position of facial bones that are adjacent to cartilage which will disappear; that is, cartilage has both direct and indirect roles in facial morphogenesis. At the tissue level, cartilage is also important in a greatly prolonged temporal manner. Chondrogenic and osteogenic cells have a close relationship prior to differentiation, and endochondral bones have a long window of development time for change beyond the initial formation of a cartilage template.</p>","PeriodicalId":50965,"journal":{"name":"Anatomical Record-Advances in Integrative Anatomy and Evolutionary Biology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary (developmental) changes of fluorotic roe deer enamel are hypomineralization and microstructural aberrations, including enamel hypoplasia. The hypomineralized fluorotic enamel is whitish-opaque on eruption and gets stained following tooth eruption. Moreover, it is prone to excessive wear and mechanical breakdown, resulting in posteruptive enamel lesions. These posteruptive lesions can morphologically clearly be distinguished from hypoplastic defects. Due to the impaired mineralization of fluorotic enamel, affected cheek teeth lack the prominent enamel ridges normally present on the occlusal surface. The severity of dental fluorosis typically varies among the permanent mandibular cheek teeth of more severely fluorotic dentitions. While the permanent premolars and the third molar show marked pathological changes, the first molar is largely unaffected, and the second molar is less affected by fluorotic alterations. These differences have been related to protective mechanisms (placental barrier and milk-blood barrier to fluoride) operating during prenatal and early postnatal life that prevent excessive plasma fluoride levels during crown formation of the M₁ and partly also of the M₂ in individuals from fluoride-polluted habitats. Observations on the fluoride content of early-formed and late-formed dentin of cheek teeth from individuals with severe dental fluorosis support this hypothesis. The findings in the European roe deer constitute the most comprehensive characterization of dental fluorosis currently available for a wild ruminant species.</p>","PeriodicalId":50965,"journal":{"name":"Anatomical Record-Advances in Integrative Anatomy and Evolutionary Biology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, especially for visiting scientists working on museum collections, it is not uncommon to collect data in multiple rounds, with interruptions of weeks or years. To explore the impact of time lags on Procrustes shape analysis, I repeatedly digitized the same landmarks, on photographs of crania of adult yellow-bellied marmots, at progressively longer time intervals, ranging from a few hours to days, weeks and, in one case, many years. Using a battery of methods, I found that there is indeed a time-related systematic ME suggesting the possibility of a \"visiting scientist effect\" biasing shape patterns. However, the relationship between time lags and the magnitude of the bias is not simple and linear, but complex. Interestingly, the impact of the bias on the results of tests of sexual dimorphism and allometry is modest, and mostly negligible, unless the design of the data collection is highly unbalanced. When this happens, as in a simulated case where females are digitized first and males only later (or vice versa), the effect of the bias on tests of biological variation becomes important and can even lead to opposite conclusions on group differences. I will discuss when systematic ME in landmark data is more problematic and how to try to mitigate the impact of a potential \"visiting scientist effect\" on shape analyses.</p>","PeriodicalId":50965,"journal":{"name":"Anatomical Record-Advances in Integrative Anatomy and Evolutionary Biology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143755818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Morphologically complex and phylogenetically diverse, the anatomy of EBOs has been described in a small number of taxa that possess this structure, in many cases without a thorough investigation at the microscopic and ultrastructural level. Additionally, the evolution of EBOs has not been rigorously examined within a phylogenetic comparative context, leaving many unanswered questions about how the morphological diversity of EBOs relates to historical patterns and ecology. We characterized the anatomy, histological architecture, and structural patterns of EBOs in 13 otomorphan species belonging to the orders Clupeiformes, Gonorynchiformes, and Characiformes; this sampling includes Cetengraulis edentulus, Nematalosa come, and Tenualosa thibaudeaui, in which the presence of an EBO has not been previously documented. We then conducted a preliminary investigation of relationships between otomorphan EBO anatomy, phylogeny, and diet. Patterns of anatomical diversity were best explained by variation along five morphological axes: shape, size, associated gill rakers, muscularity, and adiposity. EBOs consisted of bilaterally paired diverticula surrounded by layers of circumferential and longitudinal muscle and varying amounts of adipose tissue. Papillae were found in the epithelium lining the diverticulum of each organ; they varied in length and width along the proximodistal axis of the diverticulum and were studded with mucus-producing cells. We found that EBO anatomy was not strongly correlated with phylogenetic relatedness but was moderately correlated with diet in some instances. We hypothesize that EBOs have independently evolved in Otomorpha multiple times via a conserved developmental pathway that makes use of the same underlying tissue types to construct morphologically diverse structures. These findings suggest that there are multiple ways to build an EBO using the same basic anatomical components to achieve the same functional goal-the aggregation of small prey.</p>","PeriodicalId":50965,"journal":{"name":"Anatomical Record-Advances in Integrative Anatomy and Evolutionary Biology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143755819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Human facial musculature is highly variable across individuals, but to date, whether other primate species exhibit a similar level of inter-individual variation is unknown. Whether individual-level variation in facial musculature covaries with significant differences in facial movement within the same individual is also unknown. Here, we use facial dissection data from 31 adult rhesus macaques, the largest sample to date, to quantify inter-individual variation in facial muscle presence. We used a subsample of eight individuals to measure covariation between facial muscle presence and the presence of external facial movements (action units in the Facial Action Coding System, or FACS). We found, in contrast to humans, limited inter-individual variation in muscle presence, but the zygomatic region exhibited more gross anatomical variation in muscle presence and morphology than any other region of the macaque face. We also found a good correspondence between facial muscle presence and the presence of the associated action units. Our results indicate that the observed variation in rhesus macaque facial expressivity is not likely driven primarily by variation in facial muscle presence but may instead be due to other factors such as learned behavior and/or physiological differences. These findings provide insight into the anatomical basis of inter-individual variation in facial behavior in primates and suggest potential differences in variation between humans and other primate species.</p>","PeriodicalId":50965,"journal":{"name":"Anatomical Record-Advances in Integrative Anatomy and Evolutionary Biology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143651875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, available specimens of the Early Jurassic Vieraella herbstii from Patagonia, which consist of dorsal and ventral imprints of the incomplete, partially articulated skeleton of a single individual, are thoroughly redescribed. Although we comment on its known features, we focus on those that had been misinterpreted or overlooked previously. Among other features, we address the relative proportions of the skull regions and limbs, the morphology of the vomers, the peculiar articulation of the palatine flanges of premaxilla and maxilla that suggests the presence of well-developed cristae subnasales, and the presence of prepollex. The most surprising, significant findings are the presence of stapes, indicating the possibility of a complete tympanic middle ear, and of a short, tapering urostyle and postsacral vertebral elements. Based on available information, we present partial reconstructions of the pectoral girdle and the skeleton of Vieraella in the dorsal aspect. Discussion of the evolutionary significance of these features and perusal of the phylogenetic and functional analyses that included Vieraella in the taxon sampling highlight the necessity of thorough revision of the scorings and measurements, incorporating information presented herein.
