Use of the notochordal canal as a reliable proxy for prenatal stage, a case study in Ichthyosauria
Royal Society Open ScienceAbstract Determining embryonic stage is critical to assess heterochronic development between species and aids in our understanding of a clade’s evolution. Prenatal staging is difficult in extinct taxa due to the rarity of embryonic and fetal material. Ichthyosaurs are extinct reptiles with many prenatal specimens known.
