Breve resumo:
ABSTRACT: In this paper, we present the history of latex in Paleontology and its role in the field today. We discuss the methodology and advantages of latex fossil moulds, while also presenting examples of moulds of compressions/impressions of plant fossils. Latex rubber has been used to create moulds of fossils since the first half of the 20th century and it is still used in various branches of Paleontology. While the methods have stayed largely unchanged, some innovations have been introduced. We also discuss the virtues of large-scale adoption of latex in the study of paleobotanical compressions/impressions, a technique not widely used in that branch, but in which latex can provide better visualization of certain key diagnostic characters for identification. Furthermore, widespread use of latex would increase the amount of viable fossils for study.​
