Hello and welcome to I know Dino. I'm Garrett.

0:34.8

And I'm Sabrina.

0:41.2

And today we'll be talking about herarasaurus, Iski-Wualis stensis, as well as a lot of dinosaur news.

0:49.4

First in the news is an article that was reported to us by our listener and former interviewee, Josh Cotton.

0:53.4

And he pointed us to an article about stegasaurus swimming. So all of this information comes from the article,

0:58.3

Could Stegasaur swim, suggestive evidence from the Middle Jurassic track site of the Cleveland Basin in Yorkshire, UK,

1:06.1

which was published in the Geological Society of London for the Yorkshire Geological Society,

1:13.3

and written by M. Romano and M.A. White, who passed away before it was published.

and they're all from the non-marine saltwick formation, and what makes them

1:47.3

believe that they are stegosaurus tracks is that they appear to come from the ikno type of

1:52.7

Delta Potus, which was previously described in other papers, as a stegosaurus.

1:58.8

So just as some background, what an iknotype refers to is the field of science called

2:05.2

iknotaxa, and that can include ikno genera and ikno species, because, you know, taxa is just

2:12.4

the broad term for the category, and it can vary in its specificity.

2:18.1

So iknotaxa means track ordering in Latin and it refers to basing a taxon like a species
