- gus_massa 16d ago> The Spanish Diplodocus lived roughly 150 million years ago near the end of the Jurassic period. > [...] > According to the team, the presence of Diplodocus in Iberia offers strong evidence that dinosaurs moved between North America and Europe during that era, likely crossing temporary land bridges that appeared as the proto-North Atlantic Ocean periodically receded. I want a map! I found this: https://www.sciencephoto.com/media/167017/view https://www.sciencephoto.com/media/167017/view Is it the correct map? Is there a land (ice?) bridge between Newfoundland and Portugal? Am I interpreting it correctly?
- artisinal 16d agoWe could save a lot of money and emissions if we brought the continents back together! Imagine Paris to New York by high speed train.
- loloquwowndueo 16d agoEw no, not with the Americans behaving the way they are now. The Atlantic is fine where it is thank you very much.
- saghm 16d agoAs an American...I concur. The rest of the world doesn't deserve that.
- aeve890 16d agoAmericans behaving the way they are now and Parisians mixed together? Hell on Earth
- criddell 16d agoDuring the world cup, I saw mostly very positive reports on the experiences Europeans had with Americans, and vice versa.
- artisinal 16d agoHello, you are going against the internet narrative of "america bad" please stop doing that.
- loloquwowndueo 15d agoLook for reports from the Iranian team. I bet those weren’t as widely publicized as the rosy positive ones.
- criddell 15d agoIran isn't usually described as European and I did qualify my statement with mostly.
- loloquwowndueo 15d agoI know it’s not European. Great job missing my point entirely.
- criddell 12d agoIf you thought I was claiming everybody had a great time, then you are a missing my point.
- afavour 15d agoNice on a personal level in real life but not when dealing with a population in the abstract? Say it ain’t so!
- artisinal 15d agoFair. Perhaps we can extend the Black Sea to keep those dirty Russians out of Europe
- rubidium 16d agoI would think so yes. But not an authority on this. The map is super cool though. Makes you think of the earth as something still aging since it looks clearly “earth” but with major differences.
- shagie 16d agoElse comment I made, trying to answer that same question, I found https://thepangeamap.com https://thepangeamap.com - one of the neat features is being able to put dinosaurs in the timeline. The Paleotopography selection (rather than GPlates) also gives hints about the expected height and depth of the land and sea.
- mncharity 16d ago> map! Maps.[1][2] Too far south for an ice bridge - Newfoundland is south like modern Florida - tropical. And it's the Jurassic, hot with high sea levels, so even though its continental shelf extends out towards Spain, there are no ice ages to bare it (as was the Eastern US shelf a mere 12k years ago). But Pangea is ripping apart, it's a mess with crust blocks variously uplifted and tilted, massive weathering and sediment fluxes, so... From the TFA paper[3]: During the early Mesozoic, North America and Europe were connected to form the western and central part of the supercontinent Laurasia. With the opening of the North Atlantic during the Late Jurassic and earliest Cretaceous, the region fragmented into smaller tectonic units55–58 that might have periodically formed contiguous land masses57,58 during sea level low-stands, characterized by exposure of continental margins and draining of continental interior seaways55–58. The presence of a land bridge between North America and Europe during the late Kimmeridgian-earliest Tithonian13 might explain similarities in some dinosaurs such as Stegosaurus59 and Allosaurus60. However, the absence of turiasaurs in the Morrison Formation suggests that this clade dispersed into western North America after the mid-Tithonian. Thus, unless we wish to argue that turiasaurs were actually present in the Morrison Formation but have not been found yet, a second later land connection between Europe and North America is required. Specifically, during the mid-Valanginian (c.137Ma), a dramatic drop in sea level7,55,56 potentially reconnected Europe and North America and so permitted a fi al exchange of vertebrate clades across the Atlantic. Th s Valanginian event could also explain apparent faunal exchanges between these continents proposed for the late Hauterivian-early Barremian13. Taxa that seem to disperse in the Hauterivian/ Barremian might actually have done so during the Valanginian lowstand, but gaps in the fossil record mean that the results of these dispersals might not be detected until we access better sampled post-Valanginian deposits. 58 is available with a plate.[4] 57 is old, with only low-res global plates, ggl books preview has 138 Ma on p42. 56 I skipped. 55 is available[5] but is temporally low res. There's a 2016 paper Late Mesozoic North Atlantic land bridges[6], Elsevier paywalled with excerpts, and on sci-hub. And that's my time budget.

- Arubis 16d agoThis probably is the most succinct way to write the title, but assigning nationality to dinosaurs is _weird_.
- foolswisdom 16d agoMaybe in "Iberia" instead of Spain?
- loloquwowndueo 16d agoIberia is an airline my dudes. (/s before someone comes correcting me about it)
- foobarian 16d agoNow here I thought it was the Byzantine Theme in the Caucases
- saghm 16d agoFWIW "American" might be more continental than national; my recollection is that one of the places where tons of dinosaur bones were found in the early paleontology days is Alberta.
- Arubis 16d agoI think that’s what most tripped me up. “North American” would’ve been clearer here.
- saghm 16d agoI honestly had the opposite misreading; I thought it was intentionally trying to say it also had been found in South America, but from some googling I can't find any reference to that. Wikipedia seems to have already been updated to "North America and Europe"

- Maxion 16d agoOh wow! Now that's a cool site!
- deleted 16d ago[deleted]
- higginsniggins 16d agoSo according to this map, North America was separated from Spain by a body of water when Diplodocus was alive?
- Nursie 16d agoLooks like there was a land-bridge to "Europe" around the Jurassic-Cretaceous boundary if you stick it in Paleotopography mode. (I like that mode better because it appears to show the actual landmasses at the time vs the plates with an approximation of the modern masses overlayed)
- embedding-shape 16d agoFound another page with lots of interesting maps and visualization that seems hand/human made: https://earthathome.org/hoe/sc/geologic-history/ https://earthathome.org/hoe/sc/geologic-history/ In the "Triassic to Jurassic (252 to 145 million years ago)" section further down, there is this image, which I think shows a kind of land bridge between the two continents: https://earthathome.org/wp-content/uploads/2021/11/North_America_150Ma-2000px.jpg https://earthathome.org/wp-content/uploads/2021/11/North_Ame...
- lukaszkorecki 16d agoDiplodocus?

- WCSTombs 16d agoApparently I'm a bit slow today, because my brain started completing the headline as "Diplodocus, Long Thought Extinct, ..." before my eyes could finish reading it. > The animal’s fossilized remains — 14 well-preserved tail vertebrae and several chevron bones — were unearthed at the La Tejería site near the city of El Castellar in the Spanish province of Teruel. According to Wikipedia (if I'm reading correctly), the chevron bones are also part of the tail [1]. It's pretty cool how such a small part of the skeleton can carry so much information!

- ta93754829 16d agoIs "American" a nationality where maybe "North American" a geography? I don't think Diplodocus has US citizenship...

- pbkompasz 16d agoThe Americas, sometimes collectively called America, are a landmass comprising the totality of North America and South America.
- notorandit 16d agoAccording to latest executive order, Spain has been renamed "Spanish Peninsula of America". So Diplodocus keeps being exclusively American.

- alsetmusic 16d agoOnce again, history and medicine are two fields that reliably make me happy. Dinos were my faves as a child and they continue to inspire. The way we (my family) mispronounced this one: diploDOEcus. But I also got Heredotus very wrong, so I guess it was a Midwest thing.

- ano-ther 15d agoI am not a dinosaur expert, but the headline seems off. The actual paper linked from sci.news starts with this (citations removed): > Diplodocids are known from deposits present in the U.S.A., Europe, South America, and Africa. According to the available evidence, the oldest diplodocid sauropod dates back to the Oxfordian of Europe, whereas the most recent ones are from the lowermost Cretaceous of South America and Africa. It als says that "The European diplodocid fossil record is scarce and fragmentary," but that still sounds like evidence for Diplodocus in Europe, doesn't it? https://www.tandfonline.com/doi/10.1080/02724634.2026.2718423#d1e279 https://www.tandfonline.com/doi/10.1080/02724634.2026.271842...
