概括

来自罗纪的昆虫叶采矿揭示了早期的昆虫植物相互作用. 化石证据显示了保守的采矿损害类型,并确定了古老的甲虫,和虫的血统可能是矿工.

科学领域:

古生物学的古生物学
昆虫的进化昆虫的进化
中生时期的植物.

背景情况:

昆虫草食,特别是叶子采矿,是一个重要的生态相互作用.
罗纪叶子开采的化石证据很少,这在了解其进化历史方面造成了差距.

研究的目的:

调查已知最早的化石证据,证明昆虫从中罗纪开采叶子.
记录新的损害类型 (DTs) 并确定在此期间负责采矿的昆虫群体.

主要方法:

显微镜检查2014年来自Daohugou地区的植物标本.
使用功能性养组-损伤类型系统对草象类的分类.
化石矿山的摄影记录和数据库的创建.

主要成果:

在14个标本上确定了27个采矿事件,代表了8种新的矿山损伤类型 (DTs).
在六个体育种类的属中发现了矿石:本内特塔莱,金克戈亚和皮纳莱.
可能的昆虫采矿者包括多虫甲虫,单蝶和十三形虫的基底系.

结论:

中中纪的矿山在形态上是保守的,反映了植物宿主解剖学,而不是植物遗传学.
营养假设,表明矿工利用了富含营养的内部植物组织,最能解释矿山的进化.
这项研究提供了关键的见解昆虫养策略和植物昆虫相互作用在罗纪.

The Fossil Record

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...

Non-vascular Seedless Plants

Non-vascular Seedless Plants

The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological characteristics: nonvascular, seedless vascular, and seed plants.

What is Evolutionary History?

What is Evolutionary History?

Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

Phylogeny

Phylogeny

Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

Pollination and Flower Structure

Pollination and Flower Structure

Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.
