Could not resolve location for "Barcelona, Catalonia, ES" :(

That’s what it says for my hometown unless I switch to a more recent year. The error message is a bit confusing I think, the tip to change the year isn’t super obvious.

Interestingly, Barcelona doesn’t show up until you hit 0 years ago, so perhaps it’s location is extremely recent on the tectonic scale?

Are there sci-fi stories with the premise that a character wakes up transported to a different planet except it’s later revealed that it’s actually Earth in a distant time?

[Spoiler Alert:] Original 1968 “Planet of the Apes”? It's a great visual reveal in the last moments of the film; no dialog needed.

The whole series of movies (well, the pre-2000 iterations) was recently free to watch on YouTube. They're all cheesy but the original one holds up reasonably well.

Feels like a movie-length version of a classic Twilight Zone episode, which makes sense, considering Rod Serling wrote the first draft of the film's script.

Earlier quoted context omitted.

PHP is more like birds. Technically, they're dinosaurs, but they've evolved and stayed relevant after Perl, etc. went extinct.

I believe you mean they are more like pterosaurs

I bet they mean birds, aka modern dinosaurs. This is a good 'aka' because dinosaur made baby dinosaurs who grew up to make their own baby dinosaurs. Each generation was slightly different than the last and after millions of years, the baby dinosaurs were named birds!

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].

Not quite what you are looking for, but the Malazan series has some stories spanning extremely large time scales through which multiple intelligent species evolve into existence and fade away.

It is by far, the best series I've read. Book 1 is hard to get into, and doesn't reward the reader as much, but stick with the series. It's worth it.
