蜻蜓化石 位于索爾恩霍芬的約1.5億年前的蜻蜓化石 有什么比用這只神奇的蜻蜓化石更好的方式來紀(jì)念國家化石日呢！很少有人發(fā)現(xiàn)這樣保存完好的化石，但這個化石是在德國的索倫霍芬發(fā)現(xiàn)的，那里的石灰?guī)r沉積揭示了一些最為詳細的化石，包括被稱為始祖鳥的類鳥恐龍。這只蜻蜓化石被保存在大約1.5億年前的侏羅紀(jì)時期的索倫霍芬石灰?guī)r中。它的尺寸約為5.5英寸對面，后面在美國，我們正在紀(jì)念第11個一年一度的國家化石日，由國家公園管理局主辦。這是釋放你內(nèi)心深處的古生物學(xué)家的最佳時機?；ǔＴ趪夜珗@等公共土地上被發(fā)現(xiàn)，因此公園管理員、科學(xué)家和教育工作者通常利用這一天來分享化石如何幫助我們了解古代地球上的生命。如果不能在網(wǎng)上看到最新的化石，就連最新的化石圖片都看不到。

英語原文:

What better way to honor National Fossil Day than with this amazing dragonfly! It's rare to find one so well preserved, but this one was discovered in Solnhofen, Germany, where limestone deposits have revealed some of the most detailed fossils ever found—including the bird-like dinosaur called Archaeopteryx. This dragonfly was preserved in the Solnhofen limestone about 150 million years ago in the Jurassic Period. It measures about 5.5 inches across.Back here in the United States we're marking the 11th annual National Fossil Day, hosted by the National Park Service. It's the perfect time to unleash your inner paleontologist. Fossils are often discovered on public lands like national parks, so park rangers, scientists, and educators typically use this day to share how fossils can help us understand what life looked like on an ancient Earth. Even if some events this year can't be held in person, take a moment to look at amazing fossil images online, or read up on the latest fossil news.
