Heard on the latest Common Descent podcast that there's a debate in #palaeontology about whether fossil preparators, who chip fossils out and stabilise them with resin etc., should be co-authors on scientific papers.
In #archaeology, a finds conservator does not get this type of credit. Because
a) Most can't identify or date the objects they apply their valuable skills to.
b) #Humanities papers rarely have more than three authors.
