Fósil de anthoecia de hierba dentro de esqueletos de rinocerontes del Mioceno: dieta en una especie extinta
Resumen
Las partes de hierba fosilizadas encontradas en un antiguo rinoceronte (Teleoceras major) sugieren que era anfibio y consumía hierbas silícicas. Este descubrimiento aclara la paleobiología de este mamífero extinto.
Área de la Ciencia:
- Paleontología Paleontología.
- La paleobotánica es la paleobotánica.
- Paleobiología Paleobiología.
Sus antecedentes:
- Teleoceras major, un rinoceronte extinto, poseía proporciones parecidas a las de un hipopótamo y dientes con altas coronas.
- El papel paleobiológico y la dieta de Teleoceras major han sido enigmáticos.
- Los restos de plantas silicificadas ofrecen una visión potencial de la dieta de la fauna extinta.
Objetivo del estudio:
- Para investigar la dieta de las Teleoceras mayores.
- Para aclarar el papel paleobiológico de Teleoceras major utilizando evidencia de plantas fosilizadas.
Principales métodos:
- Análisis de partes de hierba fosilizada (antoecia) encontradas dentro de la cavidad oral y la caja torácica de los esqueletos de Teleoceras major.
- Identificación de las especies de césped: Berriochloa communis, Berriochloa primaeva y Berriohldoa cf. Nueva. nueva. nuevo. nuevo.
- Análisis contextual de hallazgos fósiles dentro de los depósitos de ceniza volcánica del Clarendoniano tardío en Nebraska.
Principales resultados:
- La antocea silicificada de tres especies de pasto se identificó como residuos de alimentos dentro de los fósiles principales de Teleoceras.
- Los fósiles de plantas se ubicaron en la cavidad oral y la caja torácica, lo que indica ingestión.
- Los hallazgos sugieren una dieta que incluye cantidades significativas de hierbas silícicas.
Conclusiones:
- Teleoceras mayor fue probablemente anfibio.
- Las hierbas siliciosas formaban una parte sustancial de la dieta principal de Teleoceras.
- Esta evidencia dietética ayuda a resolver el enigma paleobiológico de Teleoceras major.

Threats to Biodiversity
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
The Fossil Record
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
Overview of Nitrogen Metabolism
Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of ammonia, ammonium ions, nitrate, nitrite, or nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.
The largest pool of nitrogen available in the terrestrial ecosystem is gaseous nitrogen (N2) from the air, but this nitrogen...

Microbes and Methanogenesis
Methanogenesis is a critical microbial process in anaerobic ecosystems responsible for the biological production of methane, a potent greenhouse gas and valuable biofuel. This metabolic pathway is primarily facilitated by methanogenic archaea, which thrive in anoxic environments such as wetlands, sediments, and animal gastrointestinal tracts. The absence of oxygen in these habitats prevents aerobic respiration, thereby favoring alternative biochemical pathways for organic matter degradation.In...
Microbes and Climate Change
Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...
Microbial Spoilage of Food
Microbial food spoilage refers to the degradation of food quality resulting from the metabolic activity of microorganisms such as bacteria, yeasts, and molds. These microbes proliferate on various food substrates depending on factors such as moisture content, nutrient availability, and storage conditions, leading to undesirable sensory and structural changes.Bacteria are primary agents of spoilage in high-moisture, nutrient-dense foods like meat, milk, and vegetables. Microbial spoilage occurs...
