And so here is a here is a concretion . A concretion is just a special type of rock that forms around an organic nucleus. You can think of like a pearl in an oyster shell.
that we've hinted at with this record. No concretions . So there seems to be something special about being close to the mountains.
that we've hinted at with this record. there are no concretions .
that we've hinted at with this record. And we can't date the concretion itself.
that we've hinted at with this record. We do think that these concretions extend deeper in time, at this interval of time.
that we've hinted at with this record. Because we seem to only find these concretions in areas that are closer to the mountains.
that we've hinted at with this record. One of the good things about concretions is that they form around the bodies, and then they can roll down the hill,
And this is where our big aha moment happened, where we went from looking for fossils like this, a bit of a needle in a haystack, to looking for concretions . And so here is a here is a concretion . A concretion is just a special type of rock that forms around an organic nucleus.
that we've hinted at with this record. Yeah, why concretions ? And why this interval of time?
Pretty incredible. Yeah, that is pretty awesome. From what you learned at this exposure from the chemistry and the concretions and all of that, are there now other places in the world where you or other people are saying, oh, well, maybe we should be looking more closely at these rocks?
that we've hinted at with this record. And in fact, paleontologists look for concretions specifically to find fossils in marine settings.
that we've hinted at with this record. So certainly in Tyler's world, prepping those fossils out of those concretions is a big deal.
that we've hinted at with this record. I guess the first one is, is why the concretions at this period of time and not before?
that we've hinted at with this record. Or was it, and it's just sheer numbers that you're only finding the concretions now?
You can maybe see the teeth sticking up in the photo. And this is where our big aha moment happened, where we went from looking for fossils like this, a bit of a needle in a haystack, to looking for concretions . And so here is a here is a concretion .
over and kicking these rocks. And again, that was our aha moment, when we realized that the fossils were inside of these concretions . And you can see why a lot of people would have walked over them, because they are very, very nondescript.
that we've hinted at with this record. There are other areas that were close to the mountains 65 million years ago, that very well could have concretions preserved as well.
that we've hinted at with this record. And to add to that, in marine sediments and ocean sediments, concretions are very common.
that we've hinted at with this record. So if you were a fossil buff or anybody is a fossil buff in the audience, you may have actually cracked open concretions
