I think I have told you before… When I go to Mexico, which I will be going this week, I study these little buggers…

They look like coral, don’t they?!

But they aren’t… they are made by bacteria…

Last week when we were in Morocco, one of the things we were looking at were some fossilized stromatolites (by the way, that’s the science name for them.) We wanted to compare: the stromatolites that are living today and what they look like to the ones from billions of year ago… to see what was similar and what wasn’t.

Scientists love to compare things…

There is a lot of controversy over what might be a real, old stromatolite and what might just be, well, chemical processes…

It’s highly controversial.. that word came out of the mouth of almost every geologist on the field trip in almost every explanation that was given.

So they let us out of the cars and there in the field to the right of the road cut they told us to get out and take a look…

Okay, that doesn’t show you what you need to see. Here’s a better view…

Just imagine this… if you had been a sheepherder, back before the pyramids were built and you and your clan were wandering this part of north west Africa, would you have looked at these “rocks” and wondered, “What in the heck are these things?!?!? Where did they come from?”

Now take a look at this:

Hint: that picture above is from Shark’s Bay, Australia, about 1 year ago.

What do you think? What are those things from the Moroccan field and what do you think that field used to look like, oh say, about 600 million years ago?

And even better, do you think if we saw something like that on another planet, that NASA could make this announcement “We have found ET!!!!”
