Incidentally, Kukalová-Peck, the describer of Mazothairos, is known as a notorious figure among palaeoentomologists. She sometimes do "overinterpretation," illustrating features of fossils that are not actually visible, and is also known for sometimes carving the fossils to match her interpretation.

People always consider Mazothairos as a representative of Palaeodictyoptera, but in fact this genus is only known from part of the thorax preserved, WE DON'T EVEN KNOW ITS WINGS! Meanwhile there are many lesser known genera that are smaller in size but have beautifully preserved wing patterns.

This is so off...
It looks like a priapulid because it's an acanthocephalan (acanthocephalans tend to look like priapulids)
A comment by OP says this doesn't match known gnathifer phylogeny, but... however doesn't it?

Okay, this question is just for the palaeontologists (*actual* palaeontologists pls, not "I have a comment").
This paper claims to have found a transitional form for acanthocephalans and the rest of Gnathifera, but to me it looks like priapulid - what do you think?

Winneshiekia youngae, an Ordovician dekatriatan chelicerate. It shares traits with e.g., xiphosurans (such as the eye ridge) and chasmataspidids (13-segmented opisthosoma).

A very unusual ancient horseshoe crab for #FossilFriday. This creature is from the Ordovician (425 million years ago) of Michigan and looks like no other horseshoe crab that we know of. This specimen also has a secret which will be revealed when the description is published shortly! 🧪⚒️

surely this would receive more attention
is this even real
