2020). During our first studies on this structure (2016), my colleague Dr Loic Costeur (curator at the NMB) and I figured out that the bony labyrinth almost fully ossifies early within the fetus gestation (around mid-gestation) in ruminants, involving a similar shape and size until the death of the individual.
