There are now 101 radiocarbon dates from the long Paleolithic and post-Paleolithic culture-stratigraphic sequence in El Mirón Cave, Cantabrian Spain. Here we report on two dates on bone from two different humans whose remains were found in disturbed surface sediments in the cave vestibule rear and that confirm the existence of burials in addition t...

The evolution of life on this planet is influenced by many factors, key among them being the means in which predators and their prey interact. Direct morphological evidence for how large mammalian predators evolutionarily respond to their presumed herbivore prey is lacking , but predator richness positively correlates with that of extinct and extan...

The long-standing assumption that aboveground plant litter inputs have a substantial influence on soil organic carbon storage (SOC) and dynamics has been challenged by a new paradigm for SOC formation and persistence. We tested the importance of plant litter chemistry on SOC storage, distribution, composition, and age by comparing two highly contra...

The Kurtzhals property is in Section 19, Township 30N, Range 3 in Cedar County, Nebraska. The present land use is agricultural row crop, but past use included hog production. Two active irrigation wells are located on adjacent properties to the west and southwest. An irrigation well was installed in the northwest corner of the property in 2022. Due...

The Ediacaran Period, spanning 635 to 538 million years ago, marks a pivotal phase in life’s evolutionary history, showcasing early multicellular animal life. This thesis examines the remarkable fossil bed, 1T-F, from the Ediacara Member of the Rawnsley Quartzite at Nilpena Ediacara National Park, South Australia, offering insights into a shallow m...

Here I present a first chapter manuscript relating to evidence of neonatal lines in the teeth of extant mammals; a second manuscript on quantitative evidence of the impact of Universal Design for Learning (UDL) on perception of accessibility in science media; and a third manuscript qualitative study on disability social justice and accessibility in...

Abstract: The Lower Ordovician (Floian) Al Rose Formation from the Inyo Mountains, California, is a deeper-water, graptolitic equivalent of the well-known and richly fossiliferous successions described from Utah and Nevada. It is considered to have been originally marginal to the Laurentian paleocontinent. It has yielded a low-diversity trilobite f...

Abstract: The trend of global cooling across the Cenozoic transformed the North American landscape from closed forest to more open grasslands, resulting in dietary adaptations in herbivores in response to shifting resources. In contrast, the material properties of the predator food source (muscle, skin, and bone) have remained constant over this tr...

The earliest fossil evidence for complex, macroscopic, community forming organisms on Earth is preserved in the Ediacara biota (575—538 Ma). While placement of Ediacaran taxa within a phylogenetic framework is difficult due to their unique morphologies that are non-analogous to the definitive metazoans of the Phanerozoic, they can be categorized in...

Researchers have sought to understand the link between the avian skull and dietary preferences for centuries by studying vision, brain size, beak shape, and the complex evolutionary relationship of the beak relative to the cranium. One group of birds of recurring interest to researchers are the raptors. The term ‘raptor’ colloquially encompasses th...
