Owing to an error in our muscle physiological cross-sectional area calculations, the range of bite force estimates for four models in our original analysis (maximum and minimum values presented in table 2 of [1]) are approximately 6% too high. This relates specifically to error in our calculation of the effect of a 20Â pennation angle on muscle physiological cross-sectional area in the sensitivity analysis carried out on our adult Alligator, Allosaurus, juvenile and adult Tyrannosaurus models. Because the error is consistent across models, none of the conclusions of the paper have changed. A corrected version of table 2 of [1] is as follows

The demise of dinosaurs and learned taste aversions: The biotic revenge hypothesis.
Ideas in Ecology and Evolution 10(1):Â 47â54Â

Numerous hypotheses have been advanced to explain the worldwide extinction event that led to the disappearance of the dinosaurs. There is considerable empirical support for the well-known asteroid impact hypothesis, and volcanic eruptions in the Deccan Traps have also been implicated. Increasingly, theories involving multiple causes are being considered, yet few of these consider how the cognitive and behavioral abilities of certain classes of animals may have differed in ways that allowed some to survive while others perished. Here we advance the hypothesis along with supporting evidence that the emergence of toxic plants coupled with an inability to form learned taste aversions may have contributed to the extinction of dinosaurs.

In our work, we reanalysed phylogenetic datasets for dinosaurs. This included a dataset assembled by Langer et al. [1] which was further modified by Baron et al. [2]. The dataset analysed in our paper incorporated the modifications made by Baron et al. [2] to the coding of multiple characters in Pisanosaurus, which was not made explicit in our manuscript (results shown in fig. 5). Also, owing to an error prior to publication, the full citation to Langer et al. [1] was not included in our paper and is provided here for clarity. Furthermore, we would like to apologize for the fact that our paper was made available online prior to the publication of Langer et al. [1], which was the result of a lack of communication with the journal on our part.
