In scientific literature, when authors are refered by the term "et al", what does "et al" mean?

example: "Taylor and Naish et all", "as discused by Dawkins et al...." etc.

'et al.' is short for 'et alii' and means 'and others' in latin.

As an aside, I recently found out that even though foreign phrases are generally italicised, it is unnecessary in some cases, like 'et al.', 'e.g.' or 'i.e.' as they are in common use in the English language.

Technically I think "et alii" is masculine, but "et al." can also short for "et aliae" in the case when the "others" all female. Sorry for being pedantic.
