A fact from Eurypterus appeared on Wikipedia's Main Page in the Did you know column on 29 May 2011 (check views). The text of the entry was as follows:

Did you know... that a fossil of the extinct sea scorpion Eurypterus (restoration pictured) was once thought to be a catfish?

A record of the entry may be seen at Wikipedia:Recent additions/2011/May.

Telson

I would think it was more likely to deter predators than serve as a weapon.--Digthepast (talk) 01:15, 23 November 2009 (UTC)[reply]

...so I'm changing the text to reflect its likely defensive nature.--Digthepast (talk) 20:13, 5 December 2009 (UTC)[reply]

It is more likely among Mixopteracea whose body and telsons were curved making it more apparent they were defensive. In Eurypteracea and others they probably served more like rudders. The 'tapering' seems more to be a result of streamlining (see Horseshoe Crab).-- Obsidi♠n^Soul 00:05, 6 November 2010 (UTC)[reply]

Carcinosoma

Carcinosoma trigona Ruedemann, 1916 is listed as a subspecies of Eurypterus remipes DeKay, 1825 in the species list. As Carcinosoma is regarded as a distinct genus, I would be inclined to remove it here, and move it there.--Digthepast (talk) 20:24, 5 December 2009 (UTC)[reply]

What is the largest Eurypterus?

Reference 15 This link does not send you to the relevant information. In addition the referred specimen is not Eurypterus remipes, its a specimen of Acutiramus. There is no record in either linked collection of any Eurypterus in excess of 30 cm and nothing close to 4 feet in length. There are reports of a YPM specimen that suggests a animals almost 2 feet long. — Preceding unsigned comment added by 130.132.173.24 (talk) 02:03, 15 December 2019 (UTC)[reply]

PRI specimen

The large 1.3m eurypterid referred to seems to have been indeterminate from the mentioned source. I reached to Director of Collections at the PRI, Dr. Gregory Dietl, inquiring what species it was. His response:

“Thank you for your message. The specimen we have on display is Acutiramus macrophthalmus. You can see an image of our specimen in an article that Derek Briggs wrote about it (the counterpart of the specimen is actually held at the Yale Peabody Museum). The PRI specimen on display that you referred to is illustrated as Fig. 9 in the attached paper.

Best wishes,

Greg Dietl“

Attached is a paper with images of the specimen described as an Acutiramus, a larger eurypterid species which could grow over 6 ft. long. Therefore this specimen would not be in the running for largest Eurypterus. 2601:444:482:7F50:D0D:382B:F334:4700 (talk) 16:41, 22 February 2023 (UTC)[reply]
