- 摘要：
- r than previously assessed fossil minimum estimates of clade age as if they were the same as cases in which they were older. However, these cases ar
Data from: Estimating age-dependent extinction: contrasting evidence from fossils and phylogenies

- 摘要：
- e rarely been applied at the species level. Here, we present a Bayesian framework to estimate extinction rates from the fossil record accounting for age
