The specimen is most comparable morphologically and morphometrically to <em>Stegoceras validum</em>. However, it is much thinner than any ‘juvenile’ example of that species, and also differs in the elongate form and radial arrangement of the surficial tubercles, as well as occurrence of radial grooves along the lateral margins of the bone. Such differences are unlikely a reflection of intraspecific variation. Instead, the Aguja specimen likely represents a previously unknown juvenile semaphoront from the southern Western Interior, referred herein to <em>Stegoceras</em> sp. and likely extends the distribution of this widespread Campanian genus. A morphometric evaluation suggests that the holotype specimen of <em>Texacephale langstoni</em>, also from the Aguja Formation, is probably an adult semaphoront of <em>Stegoceras.</em> However, both specimens represent different ontogenetic stages with dissimilar morphologies and so their potential conspecifity remains equivocal. The new Aguja specimen described herein likely represents a ‘paedomorphic’ Campanian pachycephalosaur – one where the onset of doming is displaced until well into ontogeny – a heterochronic attribute <em>Stegoceras</em> sp. shares with <em>S. validum</em> and <em>Pachycephalosaurus wyomingensis.</em> Where an adequate ontogenetic sample is available for comparison, other pachycephalosaur taxa do not seem to exhibit a similar growth progression, and so this appears to be a significant taxonomic characteristic. That some pachycephalosaurs delayed doming of the skull roof during growth is enigmatic, but it may have been an expression of sexual dimorphism, an aid in species recognition, or a response to harsh environmental conditions.</div></div>","PeriodicalId":55116,"journal":{"name":"Geobios","volume":"86 ","pages":"Pages 89-106"},"PeriodicalIF":1.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142578309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This volcanic event generated a major environmental change at ∼17 Ma (Burdigalian) and hostile living conditions for the biota of the area, at least during the time of deposition. We performed here a comprehensive study including taxonomic, sedimentological, and taphonomic aspects of the mammal assemblage recovered from this tuff deposit.

The formation of the assemblage can be linked to a normal attritional model, in which the death of the individuals and subsequent deposition and burial of their remains would have occurred gradually over time, simultaneously with the accumulation of volcanic ash, at the place of death or very close to it. The time between the death and burial would have been relatively short, in accordance with the rapid and continuous influx of volcanic ash to the depositional environment.

More than half of this diversity is from the Lower Cretaceous Jehol deposits in northeastern China, and numerous late immature and mature specimens have been sectioned for histological analysis. These specimens reveal thin cortices with low amounts of vascularization and variably-present growth lines. An inner circumferential layer is typically observed, but rarely a distinct outer circumferential layer. Here we describe the morphology and histology of two early immature enantiornithines and explore ontogenetic changes in skeletal morphology and bone formation. These specimens help to fill in a crucial ontogenetic gap between the previously sectioned embryonic specimen of <em>Gobipteryx</em> and purportedly mature or near mature specimens. In support of interpretations regarding the precocial onset of flight in Enantiornithes, the proportions of the forelimb cortical thicknesses relative to the hindlimb in IVPP V15575 is very similar to mature enantiornithines. Opposite neornithines, the bone tissue of the humerus is more mature than the tibia. Precocial development of the femur is considered plesiomorphic to Aves, thus the shift towards greater maturity in the forelimb relative to the hindlimb observed in IVPP V15575 probably reflects the apomorphic evolution of super-precocial flight in enantiornithines. Osteohistological traits in IVPP V15686 and V15575 resemble those of extant chicks on the more altricial end of the developmental mode spectrum, but individuals from later growth stages. Since ossification indicates these two specimens are very immature, this highlights the unique osteohistological development of enantiornithines. Differences between these two individuals are potentially indicative of intertaxonomic variation in enantiornithine growth strategies. However, developmental plasticity in stem birds means that morphological and osteohistological maturity are decoupled and that ossification patterns can vary even within a taxon. As such, significantly more data are required to fully understand observed differences and extract patterns regarding variation in developmental strategy among enantiornithines.</div></div>","PeriodicalId":55116,"journal":{"name":"Geobios","volume":"90 ","pages":"Pages 103-122"},"PeriodicalIF":1.6,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143928089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we reinterpret the jaw of <em>Asteriornis</em> and illustrate that the caudalmost portion of the mandibles are in fact not preserved.
