🚨new #preprint🚨
Age depth models are crucial to determine the timing and rate of past change, but are often based on simplified model assumptions that result in convenient mathematics. We built two new methods to estimate them from complex #stratigraphic and #sedimentological data to produce empirically realistic age-depth models 😁
It's open #PeerReview

Fig: 3 scenarios for the #petm, showing fluctuations in sed. rates by a factor of 20!
