Reply to comment by hazpat in Trilobite tridents could be the oldest evidence of male sexual combat — Fighting for mates may be a behaviour that dates back over 400 million years by marketrent

Eagerly awaiting your forthcoming peer-reviewed paper where you refute their in-depth analysis that the shape is most similar to modern day beetles that use their horns for jousting. No doubt your I-looked-at-this-for-2-seconds pet theory will put these so-called trilobite "experts" who "dedicate their lives to studying this type of thing" to shame.

These tridents face down. Similar to elephant or boar tusks. They may be used in combat but they appear to be perfectly located to stir up mud as there primary purpose.

Beetle horns usually face out and up more like rhinos because there primary use is different.

Like I said I'm sure you know better than these scientists who study trilobites for a living and I'm looking forward to your peer-reviewed scientific paper that supports your theory.

It's funny how you expect a redditor to provide peer reviewed opinions to counter what the authors refer to as speculation.

The significance of the paper is literally that it shows strong evidence that the horns were not for foraging/feeding in mud:

> A unique teratological specimen of Walliserops trifurcatus showing four, rather than three tines, is inconsistent with possible hypotheses connecting the trident to feeding techniques and suggests a sexually selected function. Malformations in a variety of living organisms support this conclusion. Morphometric comparisons to similar structures used for intraspecific combat in dynastine beetles show that the trident occupies a comparable shape space consistent with the hypothesis that it was a sexual combat weapon, the oldest reported example of its kind.

Have you ever written a scientific paper, or do you know any scientists? Do you think they just sit around and spout out random ideas that don't stand up to 2 seconds of idle speculation from laypeople? Because that seems to be the assumption inherent in your very confident assertion that these scientists are wrong based on your "first glance".

Are you an author on this? You sound offended that a person can use the same visual comparison techniques as the authors and come up with a different speculation. Each time you redundantly quote the article, it is a section that uses visual assessment to say the structures on these aquatic creatures "looks like" what land creatures use in combat.

In your opinion once an article is published it can't be incorrect and nobody should question it? Jenny McCarthy vibes on that.

The thing I find offensive is the arrogance and disrespect for science in general to think that your non-expert, non-peer reviewed opinion that is specifically and methodically refuted in great detail by actual experts who wrote an actual peer-reviewed paper holds any weight. It's like telling an astronomer that they're wrong about the earth orbiting the sun because to you it looks like the sun is going around the earth.

You realize they say multiple times they need more evidence to support their hypothesis right?. They aren't even sure if the species exhibits sexual dimorphism. You seem hyper invested in these authors initial untested hypothesis, you also seem to keep assuming this article has to be true because of peer review... it's literally a hypothesis open for discussion
