Lucas 2001: fossil species and genera erected on the basis of characters that have been modified by

1
Lucas (2001) fossil species and genera erected
on the basis of characters that have been
modified by taphonomic processes.
Taphotaxa are invalid because the
characteristics used to diagnose them are
artifacts of preservation.
Taphotaxa are relatively rare among taxa erected
on the basis of body fossils, but they are more
common in ichnofossils taxonomy.
