概括
这项研究回顾了圆形头骨的灭绝动物的"头"行为假说. 它澄清了术语,并讨论了潜在的脑创伤,强调需要精确地与活着的动物进行行为比较.
科学领域:
- 古生物学的古生物学
- 比较生物学的比较生物学
- 生物力学 生物力学
背景情况:
- 灭绝的种群中的头行为假设通常基于头骨形态学,与现存的动物 (如大角羊) 进行并行.
- 现有的研究经常将头与化石中扩大的顶联系起来,骨质结构缺乏直接的现代对应物.
- 术语"头"缺乏精确的定义,导致化石种类的行为解释模糊.
研究的目的:
- 复习顶形结构的化石种群中头行为假设的历史和应用.
- 提出一种标准化的术语来描述灭绝的动物的头行为.
- 分析形态和潜在的脑创伤在灭绝的头撞动物的含义.
主要方法:
- 在化石和现存的脊椎动物中对头行为进行文献综述.
- 对现存种群 (如绵羊, warthogs,野牛) 的头骨形态和战斗行为进行比较分析.
- 检查头骨结构与潜在的头诱导的大脑损伤之间的关系.
主要成果:
- 术语"头撞"是不一致的应用,缺乏具体的定义,如冲击表面,速度和速度等行动.
- 现存的种类表现出多样化的头骨形态和战斗策略,使灭绝物种的直接行为类比成为问题.
- 现存动物的脑损伤可以发生而不会损害覆盖的骨结构,这是化石解释中经常被忽视的因素.
结论:
- 需要一个清晰的术语协议来完善研究灭绝的种群中的头行为.
- 形态上的差异需要在比较化石和现存的头行为时仔细考虑.
- 了解头撞机械和潜在的伤害对于精确的古艺术动物的灭绝动物的重建至关重要.

02:56The Fossil Record
25.1K
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...

01:08Overview of the Skull
4.5K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:27Cranial Bones: Lateral View
2.2K
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...

01:14Cranial Bones: Superior and Posterior View
2.1K
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,...

01:26Bone Markings
5.2K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
