E1-03-Extreme Survivors 极限生存

You can never know how well Tyrannosaurs could count, but I imagine Mom would be a little bit perplexed when suddenly she was down to five instead of six and there was no sign of where it had gone.

For a baby Tyrannosaurus Rex, danger lurks everywhere. But at least he has a fighting chance.

For infant Sauroposeidon, it's a very different story. They are born defenseless. And alone.

If you want to have intensive parental care, you can only take care of a limited number of offspring.

If you want to have lots of offspring, you have to have little or no parental care. Sauropods took that route.

From birth, Sauroposeidon is in a race for survival.

For every 3,000 hatchlings, only 1 will make it to adulthood.

And to become that one survivor, it must fend for itself for years.

For this future giant, there's just one rule-grow or die.

When we look at Sauropod tracksites, where we have tracks of hundreds of individuals all together, there's a curious thing.
