与恐龙同行（2025）

与其他肉食性恐龙匕♥首♥状的牙齿不同
Unlike the broad blade like teeth of other predatory dinosaurs,
棘龙的牙齿类似于鳄鱼呈光滑的圆锥形
Spinosaurus teeth are smooth and conical like a crocodiles,
它们都以鱼类为食
because they both eat the same food.
作为捕食鱼类的动物
This is basically your main piece of anatomical weaponry
这套生理构造堪称终极武器
if you're going after fish.
没错
Oh yeah.
专门制♥服♥那些滑溜溜的大鱼
Big fish, stabbing slippery prey.
细长的嘴部有60多颗这样的牙齿
With more than 60 of these teeth in its long jaws.
使得棘龙足以猎杀体形最大的鱼类
Spinosaurus was able to tackle the largest fish.
试想一下要制♥服♥庞大的
Imagine having to hold on to a big saw skate,
垂死挣扎的帆锯鳐
fighting for it's life.
是啊 的确不容易得手
Yeah, it definitely wasn't an easy catch.
当然 猎物会拼命挣扎
Yeah, I mean they put up a real fight,
必须要有这种致命武器才能控制住猎物
you need these kind of killing tools right to, to hold on to the prey.
索贝克演化出的蹼足与利齿
Webbed feet and spikey teeth are critical adaptations
在捕猎时不可或缺
that Sobec will need to make a catch.
即便如此
But even so,
成功
success...
也并非十拿九稳
is far from guaranteed.
虽然索贝克速度更快
Although Sobec is faster,
帆锯鳐却更为灵活
the saw skate is more agile.
索贝克必须改变策略
Time for a change of tactics.
像鲨鱼般
Attacking from below
从下方发起伏击
like a shark.
成功了
Success.
不过把猎物带回幼崽身边
But getting his catch to his family
也是项艰巨的任务
won't be easy.
这次索贝克决不会放弃自己的猎物
This time, Sobec is no mood to give up his kill.
它带领全家来到这片丰饶的水域
By leading them to this land of plenty,
成功地保障了幼崽的生存
Sobec has ensured his babies survival.
然而为了这场胜利
But his moment of triumph...
索贝克付出了惨重的代价
has come at a terrible cost.
这些小碎片
So these are small parts
来自于这只棘龙的股骨
of the femur of the thigh bone of our Spinosaurus.
对 哇
Yeah, wow.
很棒的发现吧
That's really nice, right?
索贝克的骨骼化石切片
Slices cut through Sobec's bones
预示着一个沉重的结局
have a disturbing story to tell.
我们检测了骨骼切片
We looked at some of the sections,
通过显微镜观察生长线
we looked at the growth lines under the microscope
以确定它的年龄
trying to look at the age,
结果还不错
they came out pretty nice,
虽然不像树木年轮那样容易辨别
you know it's not as easy as reading growth lines on a tree,
但我们最终将这只棘龙死亡时的年龄
but we can narrow it down to an age of
锁定在17至19岁之间
17 to 19 years at death.
好的 它的年龄不算大
Okay, so he wasn't that old.
没错 也就刚刚成年 年龄不大
Yeah, like a young adult ish you know.
其他大型肉食性恐龙的寿命
Other large predatory dinosaurs are thought to have had a life span
大约为30年
of about 30 years.
而索贝克的骨骼显示
But Sobec's bones
它刚刚成年就死了
reveal he was barely an adult when he died.
也许它本可以活得再久一点
So maybe he could have lived a little bit longer.
是啊 我们假设棘龙也能活
Yeah, if we assume a similar kind of life span for a Spinosaurus
二十大几岁 三十出头
you know, late 20s early, 30s,
那它可死得太早了
it's a, a life cut short.
索贝克骨骼中隐藏的证据表明
The evidence hidden within his bones
它可能没能见证自己的幼崽长大
suggests Sobec may not have lived to see his family grow up.
为了幼崽能顺利生存
In providing for his babies,
索贝克付出了生命的代价
he has paid the ultimate price.
随着古老河流的潮起潮落
And as the great river ebbs and flows,
层层沉积物逐渐覆盖了它的尸体
it covers his body with layer upon layer of sediment.
索贝克的故事
Preserving Sobec's story
被永久掩埋在流沙之下
beneath the desert's shifting sands.
直到一亿年后
Until he is eventually found
它的遗骸重见天日
100 million years later.
