Abstract
: Origin and diversification of atypical cambial growth in fossil plants: developmental processes involved. We found a series of morphologies in the fossil record whose origin can only be inferred by means of ontogenetic studies. Therefore, comprehension of plant developmental processes and their resultant patterns are extremely important in Paleobotany. In this contribution, we exposed the relation between developmental processes and the different patterns observed in fossil plant secondary growth. Polished surfaces, peels and thin slides of silicified trunks belonging to Lycopsida, Sphenopsida, Medullosales, Corystospermales and Cycadales, were studied. We ide...
