Uberon Taxon note : In early lobe-finned fishes and ancestral tetrapods, the lacrimal bone is a relatively
large and robust bone, running from the orbit to the nostrils. It forms part of the
side of the face, between the nasal bones and the maxilla. In primitive forms, it
is often accompanied by a much smaller septomaxilla bone, lying immediately behind
the nasal opening, but this is lost in most modern species. The lacrimal bone is often
smaller in living vertebrates, and is no longer always directly associated with the
nasal opening, although it retains its connection with the orbit. The bone is entirely
absent in living amphibians, as well as some reptilian species[ISBN 0-03-910284-X];
