Ancient Trilobites Had Crystal Eyes

I learned something. Amazing how nature solve problems in different way

There was an article that came out, maybe a few months back, that disputed this. It had to do with crane fly fossils. Apparently they recently found crane fly fossils which also had calcite in their eye lenses. Modern crane flies do not have calcite in their lenses. So researchers believe now that the calcite found in trilobites are due to the fossilization process.

I just found the article and I am having

trouble trying to transfer the link to this post.

The title of the article is:

"Fly fossils may challenge the idea of ancient trilobites crystal eyes." for anyone interested in reading it.

While having trouble attaching the think, I had a feeling @Fossildude19

would come through for us! And I was right! Thanks Tim!

Brigitte Schoenemann, the preeminent trilobite eye specialist, was quoted in the article and does not agree with this hypothesis:

 

But physiologist Brigitte Shoenemann [sic] at the University of Cologne in Germany is sticking with the idea that living trilobites saw through lenses that were mainly calcium carbonate. One advantage is the mineral’s power to strongly bend incoming light underwater, a help in collecting and focusing ample illumination. Also, she says that trilobite eyes that fossilized under a variety of conditions nonetheless show such lenses. She’s prepared to accept that crane flies didn’t see through mineral crystals but is not ready “to raise this singular finding, as excellent as it may be, to a general principle touching trilobites.”

Thank-you for bringing this up. I only mentioned the article in an effort to show a different side to the story. I wasn't implying that this article should be taken as being correct.
