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.
