Dear Hulbert,

Thanks for information on ICZN article 72.5.3. However, artificial casts and 
moulds may be indispensable in taxonomical studies and have to be used as 
types. For example, the entire morphology of microborings are commonly too 
difficult to describe and illustrate without making casts. Situated within 
opaque substrates, the casts have to be etched out. As such, the natural 
substrates and original microborings are gone. Is there a solution on such 
cases?

Best PaleoGreetings,
Jan Nielsen
