The Quetzalcoatlus – one of the largest pterosaurs that ever lived – was able to… fly?!

That doesn’t sound right.

I mean, look at this thing – it’s the size of a giraffe!

However, giant pterosaurs’ ability to fly is really well-established in the scientific community.

So how on Earth did this giant manage to fly?

Hi, I’m Ever and this is MinuteEarth.

Thanks to the fossil record, we know that pterosaurs had wings with elongated hand bones, just like every other flying vertebrate. But simply having wings doesn’t mean you can actually fly.

If you’re too heavy for the size of those wings – or if you can't flap them fast enough – you’ll never get anywhere. And compared to the biggest flying creatures alive today – the Kori bustard, or the wandering albatross, or even the Andean condor, depending on how you measure it – the Quetzalcoatlus was way, WAY bigger.

But, despite this giant pterosaur’s wingspan, scientists estimate that it was only about as heavy as a large pig.

Now with the wing-to-mass ratio looking more decent, giant pterosaurs still needed to be strong enough to flap them.

And while wing muscles themselves aren’t preserved in the fossil record, we know pterosaurs had huge bumps in their forelimb bones and highly modified breastbones, with ample attachment space for powerful chest muscles – just like modern flying birds do.

So it’s reasonable to believe their wing muscles were pretty brawny.

On top of that, pterosaurs had mostly hollow bones that increased the volume of their respiratory system – again, just like modern flying birds – which allowed them to deliver tons of oxygen to all those flight muscles!

All this likely helped a Quetzalcoatlus’s big body stay aloft once it was in the air.

But getting into the air in the first place is the hardest and most energy-intensive part of flight.

Flying birds use their strong leg muscles to launch themselves into the air; that’s why the bigger a bird is, the larger and more powerful its legs tend to be.

Giant pterosaurs were so huge that, in order to jump into the air like birds, they would have needed truly gigantic legs that would have made them definitely too heavy to fly.

So they solved the whole launching problem in a different way: they used their powerful wings for the dual purpose of taking off and flapping.

And this strategy is so efficient, that bats independently evolved it as well.

By the way, I think that this is my favorite fact about giant pterosaurs –and bats, of course.

Once you look at all the evidence and the facts, it makes perfect sense that these giant pterosaurs could truly soar.

They might look too big and wonky, but the Quetzalcoatlus was about as close as we’ve ever come to a flying pig.

Pigs these days, of course, rarely fly.

And – sorry to be a downer, especially after that uplifting video - but in a lot of places, the conditions they’re kept in are heartbreaking.

As someone who loves animals, I hate to see any animal suffering so much.

That’s why we want to help make a genuine positive change with today’s sponsor, FarmKind.

FarmKind helps improve the lives of animals by recommending expert-reviewed, top charities whose work really makes a big difference.

Like Sinergia Animal, which is helping end the inhumane practice of keeping breeding pigs confined in tiny crates.

FarmKind never takes a cut of your donation; it all goes to the charities helping animals.

If you sign up for just $15 bucks a month, that’s just 50 cents a day, you'll save 350 animals from unnecessary suffering in your first year. Use the code MinuteEarth for a 50% boost on monthly donations.

If even a fraction of this community did that, we'd transform the lives of hundreds of thousands of animals. Check out the description for more info. Thanks FarmKind.

FOR YOU

你能學到什麼

通過這段影片，你可以鍛鍊英語口語練習中的兩個關鍵技能：一是如何清晰表達複雜科學概念（如描述古生物飛行機制），二是自然融入贊助資訊的口語邏輯。同時，影片中主持人的講解節奏適中，非常適合用來練習“shadowspeak”技巧，提升聽力理解與口語輸出的同步性。

注意這些發音現象

影片裡有不少連讀和弱讀需要關注：比如“doesn’t sound right”中“doesn’t”的尾音/t/弱化為喉塞音；“wing-to-mass ratio”中“wing-to”連讀為/wɪŋtuː/；“all this likely helped”中“all this”連讀為/ɔːlðɪs/。這些連讀技巧能讓你的口語更接近母語者水平，也是“看YouTube學英語”時需要重點模仿的部分。

像母語者一樣表達

模仿主持人的節奏和重音是提升口語的關鍵。比如“the Quetzalcoatlus was about as close as we’ve ever come to a flying pig”一句，重音應放在“Quetzalcoatlus”“close”“flying pig”上，通過輕重對比突出核心資訊。此外，主持人在解釋科學原理時，會用“However”“But”“So”等連線詞來調整節奏，這些詞後的短暫停頓的也需要注意。利用“shadowing site”提供的逐句跟讀功能，反覆練習這些細節，能有效提升口語的流暢度和自然度。

影片中的語法

說話人最常用的結構，並附上影片中的原話：

結構	影片中的用法
被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的	is brought · aren't preserved
定語從句 who / which + 從句 — 補充說明人或事物	someone who loves · Animal, which is

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
