What is this?

According to the news I read, that was found along with many other sea creatures recently in the Antarctic expedition...

And the moment I saw it, I kind of think that it looks like a trilobite... just wondering if anyone else think so. Possibly say more about it, coz I am not very specialized in trilobites, so I'm not sure if it has the features of a trilobite or not. Plus, evolution converges sometimes, and I won't be surprised if it turns out to be a flattened shrimp species or something...

But still, I want thoughts on it...

That sure does look like a trilobite, but they went extinct some 400 MYA, so I would think it is some form of horseshoe crab.

I would have to agree that there is no way that is a trilobite, a horseshoe crab is definitely the more likely option.
Why can't this be left blank?

Yeah, that's what I am thinking too (about the extinct thing I mean), but who knows, the Coelacanth was thought to be extinct as well (granted, it was a shorter time ago, but then again...)

I guess it could be some form of the horse shoe crab...

Like I said, I wouldn't be surprised if its something else thats common and evolved into that.

EDIT:

Found another one on the internet. Yeah, it does look like a trilobite, but then again...

I am very interested, you couldn't find anymore information in the article?? What a cool critter.

Interesting.

I have read about that Antarctica expedition as well, some very interesting finds.

This creature does look VERY VERY similar to trilobites.

I can tell you that it is not a horseshoe crab though, we know this because trilobites have horizontal segments in the dorsal region of their abdomen region, horseshoe crabs do not.

I think that the trilobite is definitely related to the trilobite.

Or it is quite possible this is a trilobite and that our assumptions that they went extinct are incorrect. The world is huge and the Antarctica until recently was not explored to the amount it is now.
