Reference of "the same"

Hello everyone,

While translating a paper, I have came across the following sentence:

We used lognormal priors for fossil-based calibration points, and normal priors for calibration points based on new land connections between land masses, and the same calibration points:

... and, in the following, the authors have presented a list which its items are not "calibration points". I'm not totally familiar with this statistical-based part of this biology oriented paper. Is it possible for you to guess the reference of "the same calibration points" solely from the above sentence or you need more information?

Thank you so much for your time.
