Resumen
Un fósil masivo de mono, Protopithecus brasiliensis, descubierto en Brasil, revela rasgos únicos que combinan las características del mono aullador y del mono araña. Este hallazgo remodela nuestra comprensión de la evolución de los primates en América del Sur.
Área de la Ciencia:
- Paleontología Paleontología.
- Evolución de los Primates Evolución de los Primates
- Biología Neotrópica Biología Neotrópica.
Sus antecedentes:
- Los descubrimientos fósiles de monos del Nuevo Mundo son raros, especialmente los esqueletos completos.
- La comprensión previa de la diversidad de los primates del Pleistoceno en América del Sur era limitada.
Objetivo del estudio:
- Describir y analizar un esqueleto fósil notablemente completo de un mono de gran tamaño del Nuevo Mundo.
- Reevaluar la clasificación taxonómica y el significado evolutivo de Protopithecus brasiliensis.
Principales métodos:
- Excavación y análisis morfológico detallado de un esqueleto de primate fósil de depósitos de cuevas del Pleistoceno en Bahía, Brasil.
- Anatomía comparada, que examina las características craneales y postcraneales en relación con las especies de primates vivos.
Principales resultados:
- Se recuperó un esqueleto completo de Protopithecus brasiliensis, con un peso aproximado de 25 kg.
- El fósil exhibe un mosaico único de rasgos: un cráneo adaptado para la vocalización como los monos aulladores y características postcraneales para la locomoción suspensiva que se ven en los monos araña.
- Esto representa el mono sudamericano más grande conocido desde el Pleistoceno.
Conclusiones:
- La diversidad adaptativa de los primates neotrópicos fue significativamente mayor en el pasado reciente de lo que se suponía anteriormente.
- Las teorías actuales sobre la evolución de las adaptaciones de los primates en los Neotrópicos requieren una revisión basada en este descubrimiento.

Carbon Skeletons
Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side chains...
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 the Axial Skeleton
The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.

Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
