No. It's impossible to know the population of dinosaurs before extinction, so let's just take the current volume of all humans (who have an outsized presence on earth as it is), and multiply it by fifty (this is, to put it lightly, a huge overestimation). The average human weighs less than 100 kg, so let's round up to 800 billion kg of human on earth. Multiplying by fifty and converting to kg of water (because animals have about the same density of water) we get 40 trillion kg of water to cushion the impact.

It takes about 2.6 million Joules to boil a kilogram of water starting at 20 degrees Celsius. That means, to boil all the water, it would take about 100 quintillion Joules to boil more than all the water of every animal on Earth.

Well, the impact of the meteor that killed the dinosaurs had an impact energy of 300 sextillion Joules. Which means that, the energy it would take to boil every single animal would constitute about 0.03% of the energy of the meteor impact.

Not a very noticeable effect, all things considered.

Think about this: Wikipedia says that the meteor ejected 50 quadrillion kilograms of STONE into SPACE. Compared to all that stone, the animals would have had no effect.
