Generally,\u003Cbr \/\u003E\r\nlocomotor studies either generate plausible configurations of single joints and\u003Cbr \/\u003E\r\ncombine them in series to predict limb poses or use myological information such\u003Cbr \/\u003E\r\nas muscle insertion and torque across a joint to generate hypothetical gaits.\u003Cbr \/\u003E\r\nHowever, these studies cannot capture the other necessary mechanical under-\u003Cbr \/\u003E\r\npinnings of gaits, such as the function of joint capsules during dynamic loco-\u003Cbr \/\u003E\r\nmotion. Moreover, many of these studies focus exclusively on the appendicular\u003Cbr \/\u003E\r\nskeleton, occluding any role of the axial column in stable gaits. Currently, no\u003Cbr \/\u003E\r\nmethodologies are proposed to capture such mechanical information in extinct\u003Cbr \/\u003E\r\ntaxa. However, paleobiologists can experimentally extract information akin to\u003Cbr \/\u003E\r\nthat arising from such extant animal study through a process of modern fossil\u003Cbr \/\u003E\r\nreconstruction as a proxy of once-living organism morphologies.\u003Cbr \/\u003E\r\nIn this talk, I will briefly review the process of defossilization. I will sub-\u003Cbr \/\u003E\r\nsequently discuss my current work using defossilized models to investigate ver-\u003Cbr \/\u003E\r\ntebral joint damping and stiffness metrics toward my ultimate goal of under-\u003Cbr \/\u003E\r\nstanding the nature of mechanical work performed by spine and, finally, its role\u003Cbr \/\u003E\r\nin total body locomotion. I will conclude by discussing the next steps in further\u003Cbr \/\u003E\r\ndefossilization and collaborations with bio-inspired roboticists\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EHosted by: Dr. Jennifer McGuire\u003C\/p\u003E\r\n","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EA Paleobiological Search for Dynamic Gaits in our Paleozoic Ancestors\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"A Paleobiological Search for Dynamic Gaits in our Paleozoic Ancestors"}],"uid":"36506","created_gmt":"2023-09-21 15:46:41","changed_gmt":"2023-09-21 16:33:11","author":"rbailey74","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-09-28T11:00:00-04:00","event_time_end":"2023-09-28T12:00:00-04:00","event_time_end_last":"2023-09-28T12:00:00-04:00","gmt_time_start":"2023-09-28 15:00:00","gmt_time_end":"2023-09-28 16:00:00","gmt_time_end_last":"2023-09-28 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"(791 Atlantic.
