几百万年前的地球长什么样
What did Earth look like X million years ago?
2018 — 2022，它一次次回到首页
黑点是上首页（≥ 50 分）的那次投稿，空心点是没冲上去的投稿，点越大分数越高。
导读
一个交互式 3D 地球可视化工具：输入任意年代（如 2.6 亿年前），即可查看地球当时的板块构造与海陆分布。它改编自学术项目 GPlates，地图素材来自地质学家 Christopher Scotese 的 PALEOMAP 项目。
为什么经久不衰：它把枯燥的板块构造数据变成人人可玩的 3D 体验，多次登上首页仍让人着迷——输入自己的家乡坐标，看看几亿年前它在哪。

作者解释技术原理、精度限制，并澄清它并非恐龙查询工具
大家好，这是我做的。它基于学术项目 GPlates 改编，该软件供地质学家研究板块构造数据。定位精度方面，虽然模型给出精确结果，但应视为约 100 公里内的近似值。球面贴图由 PALEOMAP 项目的地质学家 Christopher Scotese 博士提供。至于为什么查不到你的位置——从地质学上讲，你所在的地方当时可能还不存在。另外，尽管标题如此，这个可视化并不是用来展示恐龙或化石清单的；想查附近的化石数据，请用古生物学数据库导航器。

Hi HN, I built this. It's been posted several times before, so I can answer some common questions: How does this work? I adapted GPlates [1], an academic project that creates desktop software for geologists to investigate plate tectonic data. Is the geocoding accurate? Even though plate tectonic models return precise results, you should consider the plots approximate within ~100km. In my tests I found that model results can vary significantly. I chose this model because it is widely cited and covers the greatest length of time. How should I interpret the maps/colors? The graphics that wrap the globe are provided by Dr. Christopher Scotese, a geologist who runs the PALEOMAP project. You can learn more about the project and the creation of the rasters here [2]. You might also notice some old national borders. I just work with what I can get! Why can't it look up my location? Your location probably didn't exist at the time, geologically speaking. Try switching to closer to present day (e.g. 66 Mya) Where are all the dinosaurs? Despite the title of this post, the visualization isn't really meant to show an exhaustive list of dinosaurs or fossils (the list doesn't even show on mobile). If you want to dig into data on fossils near you, check out the Paleobiology Database Navigator [3].

板块漂移让同一山脉如今横跨大西洋两岸
一个有趣的玩法：把时间调到 3.4 亿年前，看阿巴拉契亚山脉的走向。你甚至可以在西班牙和爱尔兰徒步一段阿巴拉契亚步道——国际阿巴拉契亚步道确实延伸到了那里。

One of the neat bits from this is going to 340 Mya and look at where the Appalachian mountain range runs. You can hike part of the Appalachian trail in Spain https://www.geologiadesegovia.info/the-international-appalachian-trail-spain-chapter/ and Ireland https://iatulsterireland.com https://en.wikipedia.org/wiki/International_Appalachian_Trail
标题有误导性，但可视化本身很出色
真希望标题改得不那么误导，我花了太久找不存在的功能。不过这确实是个很酷的可视化，展示了海洋和板块如何随时间演变，很喜欢！

Dang, wish this title was updated to be less misleading. I spent way too long looking for functionality that didn't exist. The author (not same person as poster) posted in the comments: > Where are all the dinosaurs? Despite the title of this post, the visualization isn't really meant to show an exhaustive list of dinosaurs or fossils (the list doesn't even show on mobile). That said, this is a really cool visualization of how the water fill and plates evolved over time. Love it!
恐龙时代竟然没有草，颠覆常识
上周我在蒙大拿挖恐龙化石，领队提到那时还没有草，只有大量蕨类植物，因为草还没演化出来。想到恐龙时代的大部分时间里地上只有叶子和蕨类，我大为震撼。

Last week I was in the field digging dinosaurs in Montana, when one of the dig leaders mentioned there was no grass back then, just lots of ferns, because grass hadn't evolved yet. It kind of blew my mind that for most of dinosaurs, there was just a lot of leafs and ferns. Here's some pictures for context (https://imgur.com/a/rE5wwc4), when you're out where most dino bones are found, you forget that it may have been a lush landscape of riverbeds approaching the ocean coastline, or that it may have been a dry arid desert landscape like in the land before time movies. Regardless, it's odd to imagine all of it, with no grass.
