Welcome to NAPC 2019! Thank you for making the journey to Riverside from all corners of the globe to participate in this meeting. We are delighted to have participants from 34 countries attending, and that attendees include hundreds of students, and also many teachers and avocational paleontologists.

Wide interest in NAPC11 allows us to offer a rich program of activities, including over 40 symposia and topical sessions with associated workshops and other forums, varied fieldtrips, and a slate of technical workshops both on campus and in sister organizations in the So Cal area.

Our approach has been to solicit proposals that reflect the current interests of the community at large and we extend our most grateful thanks to all who have worked to produce such a varied and, we trust, stimulatingly diverse program.

Thank you again for coming to Riverside! NAPC 2019 Organizing Committee Members:

The Paleontological Society is committed to safe and inclusive events and meetings for all attendees. The Code of Conduct https://paleosoc.org/ethics-and-inclusion/ applies to all members of the Society and to all participants in Society and Society-sponsored events.

In this spirit, the Paleontological Society is implementing “This IS PS” (Inclusive and Safe Paleontological Society) to help ensure adherence to the Code of Conduct at Society-sponsored events. If you are the subject of or witness prohibited behavior at a Society-sponsored event, immediately notify any member of the This IS PS team. Team members can be identified by buttons with the This IS PS logo.

The This IS PS team comprises several Society member-leaders who have been trained to receive and give reports of any incidences of prohibited behavior at Society-sponsored events. This IS PS liaisons will listen respectfully without assumptions or judgment. This IS PS liaisons will confidentially report incidents to the Society Ethics Committee to ensure that all parties involved receive appropriate consideration and follow-up. Anyone subject to or witnessing behavior that constitutes an immediate or serious threat to public safety or a criminal act should contact 911. Those witnessing a potential criminal act should also take actions necessary to maintain their own personal safety.

Those who violate the Paleontological Society’s Code of Conduct at an event may be asked to leave the meeting immediately, 3 without refund.
