Name?

Anyone know where the name comes from? DS (talk) 14:37, 2 November 2008 (UTC)[reply]

Most of these critters were named by Walcott 1910-1918. Sometimes he used geographical names, e.g. Canadia, Burgessia, Opabinia, Yohoia. I've Googled and checked Gould's Wonderful Life, and got no clues about the etymology of Wiwaxia. -- Philcha (talk) 16:40, 2 November 2008 (UTC)[reply]

~~I believe it's named after either "Wiwaxi Gap" or "Wiwaxi Peak" [1] [2], probably 'Peak, as the view is prettier.~~ Wiwaxy Peak--Mr Fink (talk) 17:08, 2 November 2008 (UTC)[reply]

Nice finds, Mr Fink! Unfortunately we can't use these as sources in the article, but it's nice to know Walcott was consistent. -- Philcha (talk) 18:27, 2 November 2008 (UTC)[reply]

I read somewhere that it comes from a Native Americad word wiwaxy meaning "windy". — Preceding unsigned comment added by 96.224.212.221 (talk) 00:07, 17 August 2012 (UTC)[reply]

Yes, the names of the geographical features in the area were usually from First Nation languages. The name for Wiwaxy Peak does come from the Nakoda word for "windy". Compare with Waptia which was named after Mount Wapta, whose name in turn comes from the Nakoda word for "running water".-- OBSIDIAN†SOUL 00:51, 17 August 2012 (UTC)[reply]

Lesson of stratigraphy

The Lower-Middle Cambrian boundary in the global geologic time scale of the International Commission on Stratigraphy still is not definitely. But two candidates are offered:

FAD of Oryctocephalus indicus is the the base of the Zone Oryctocephalus indicus, chinese standatr of the Lower-Middle Cambrian boundary.
FAD of Ovatoryctocara granulata is the base of the below lying Zone Ovatoryctocara granulata, russian standatr of the Lower-Middle Cambrian boundary.

Chinese lagerstate "Kaili Biota" has been found in the Zone Oryctocephalus of the middle part of the Kaili Formation. See http://jpaleontol.geoscienceworld.org/content/vol84/issue4/images/large/i0022-3360-84-4-668-f03.jpeg Thereby, Wiwaxia taijiangensis uniquely has an lower Middle Cambrian age.

add svg image

I have uploaded a .svg conversion of the Burgess_scale_Cor.png file to Wikimedia (Burgess_scale_Cor.svg), not sure how to append to Dinoguy2's original entry w/o breaking something. Anyone wants to before I get it figured out perfectly welcome. Thanks & good work! Sargon3 (talk) 02:17, 26 January 2012 (UTC)[reply]

Chengjiang

They first appeared in Chengjiang as the species that was founded in 1994. Late Early Cambrian or Chengjiang you choose. — Preceding unsigned comment added by 98.177.220.111 (talk) 14:22, 20 January 2013 (UTC)[reply]

Chinese Wiwaxia taijiangensis Zhao, Qian et Lee, 1994 known from Kaili formation, lower Middle Cambrian. Chengjiang fauna is other Chinese lagerstatten known from Lower Cambrian deposits. Aleksey (Alnagov (talk) 14:42, 20 January 2013 (UTC))[reply]

Issue with header image

The header image shows an adult and juvenile Wiwaxia. Both have Sclerites in the picture even though juveniles did not have them in real life—only the adults did. I like the visual style of this image, but maybe someone should replace it with a more recent and accurate reconstruction. Entelognathus (talk) 04:15, 15 March 2021 (UTC)[reply]

Castle Bank 2023

I presume the 'Wiwaxids' mentioned in One of the world’s greatest fossil finds made in Wales (msn.com) should be mentioned here.and the matter can be pursued further. Jackiespeel (talk) 20:09, 1 May 2023 (UTC)[reply]
