In 1996 Hilton founded Operation RubyThroat, an online database that allows citizens throughout the hummingbird's range in North and Central America to share their observations and data.

现年73岁的富尔顿在过去的40多年时间作为消遣或协助专业人员和同行的业余地质学家一直在辛辛那提地区富含化石的地质层寻找证据，功夫不负有心，2001年迎来了职业生涯的辉煌时刻，当时古生物协会认可了他的成就授予他哈勒尔L。

In the respect of plant geography, combining with the situation that plaeogeography, fossils of cycads, present the diversity of cycads of China and the evolutionary process of cycads, think that southwestern region of China are distribution center of plants of Cycadaceae and the originated center.

在地理分布方面，结合古地理、古苏铁植物化石的情况及现代中国苏铁科植物的多样性及苏铁科植物的演化过程等方面分析，认为中国的西南地区为苏铁科植物的分布中心，也是起源中心。

Fleshy flattened twigs scarcely or sparsely branched;2.Leaf loosely spirally arranged,decurrent,partly covered or incompletely tocompletely encircling the stem,with numerous longitudinal striations on their abaxialsurface;3.Leaf thick in substance,hypostomatic;4.Stomata arranged in longitudinal...

本文对这些化石的形态特征和表皮构造进行了详细的研究，研究结果说明它们彼此有着系统演化上的联系，应属于同一个自然类群，并提出它们的分类位置应属于伏脂杉科的希默杉亚科的新意见。

In this paper, the author discovered Solenites murrayana L. et H. from Yaojie Formation of Middle Jurassic which was an important species of Ginkgophytes in Mesozoic during environmental palaeobotany study of Lanzhou-Minhe Basin. The epidermic structure of Solenites murrayana in Yaojie Formation is similar to that of Solenites murrayana in Yorkshire Jurassic of UK by cuticular analyses.

作者在兰州-民和盆进行环境古植物学的研究中，于中侏罗统窑街组发现了中生代银杏类植物化石的重要代表穆雷似管状叶Solenitesmurrayana L.et H。，通过分析S.murrayana的表皮构造，得出与英国约克郡侏罗纪的S.murrayana具有明显相似性的特点。

An extensive dinosaur trackway site, close to the VMNH bone bed, has been studied intensively by scientists from Wyoming and Indiana. Here the BLM has built outdoor displays to help the visitor better understand how the trackways were formed.

离弗吉尼亚州自然历史博物馆发掘地不远的地方有一片广阔的恐龙脚印遗址，怀俄明州和印第安纳州的科学家对它进行了深入的研究，国土管理局也在这里建立了户外展览以帮助参观者更好地了解足印化石的形成过程。

He and his colleagues suggest, in a report in this week's Biology Letters , that previous researchers have misunderstood how feathers fossilise. In doing so those researchers have overlooked evidence of the pattern of ancient plumage.

他和同事在本周的《生物学快报》中的一份报告中提出，以前的研究者错误地理解了羽毛是如何变成化石的，结果忽略了关于远古鸟类羽毛图案的线索。

From several thousand years since the historical records until 2001 had been a lot on the Savage, Mao who山鬼such records, if we suspect that "savages" with the great apes, and then linked to the "Panda - Gigantopithecus" Fauna other animal fossils have been recorded in modern times and found that even in modern times there has been a careful research.

从数千年以来的历史记载，直至2001年为止，已经有很多关于野人、毛人、山鬼等的记载，如果我们怀疑&野人&是否与巨猿有关，则联系到&熊猫——巨猿&区系的其它动物，已有近代化石的记载和发现，甚至已有了仔细的近代化的研究。

The macrofossil records indicate that, in company with the notable climate and environmental changes, the multicellu-lar metazoans and metaphytes experienced a series of important biological evolutionary incidents in this period, such as the organ and form differentiations, the growth innovations and the further diversification of biological structures and functions.

宏体化石的记录表明在这一时期伴随着显著的气候和环境变化，发生了一系列重要的生物演化事件，多细胞的宏观后生动、植物普遍出现了组织分化，器官形成和发育创新，以及生物结构和功能的进一步复杂多样化。

More than 90% of Permiangenera of sponges, corals and brachiopods vanished in the extinction.

由于个体种化石的的数量统计随着时间的推移而变化，研究生物灭绝的古生物学家们更倾向于对称为类的有相互联系的整个物种种群进行统计研究。

Instead, we will assume that this task has been done and simply summarise the conclusions that can be drawn from it, combining the information available from the work of the fossilhungry palaeontologists with the facts gathered by the patient ape-watching ethologists.

相反，让我们假定，这一任务已经完成，我们在此只需将详细的描述作一个简单的小结，即把如饥似渴追求化石的古生物学家所提供的信息，与孜孜不倦地观察猿类的个体生态学家所搜集的事实结合起来，扼要地加以归纳。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
