Disclaimer: Data and historical records associated with Field Museum's geological collections may contain language which is culturally sensitive owing to the colonial context of the Museum's history. We have specimens collected over the last 150 years, and from all over the world. Some records associated with these specimens may include offensive language. These records do not reflect the Field Museum's current viewpoint but rather the social attitudes and circumstances of the time period when these records were made.
We welcome feedback. We are continually working with our geological records to ensure the accuracy and appropriateness of these data. As we work to promote a greater understanding of the global heritage embodied by our collections, we actively seek consultation and will revise or remove information that is inaccurate or inappropriate. We encourage and welcome help from minorities and other people historically-underrepresented in museum communities, scholars, and others to improve the data in our geological records.
