It is the earliest known ancestor of the beluga, Delphinapterus leucas, and dates from the Upper Miocene period.[2] A fossil was found in the Baja California peninsula, indicating that the family once existed in warmer waters.[3] References1. ^{{cite journal|last1=Barnes|first1=Lawrence G.|title=Fossil odontocetes (Mammalia: Cetacea) from the Almejas Formation, Isla Cedros, Mexico|journal=PaleoBios|date=1984|volume=42|pages=13–17|url=https://docubase.berkeley.edu/cgi-bin/pl_dochome?query_src=pl_search&collection=PaleoBios+Archive+Public&id=57}} {{Taxonbar|from=Q657051}}2. ^{{cite web|url=http://zipcodezoo.com/Animals/d/denebola_brachycephala/ |title=Denebola brachycephala |author=ZipcodeZoo.com |accessdate=2010-09-16 |deadurl=yes |archiveurl=https://web.archive.org/web/20120820200607/http://zipcodezoo.com/Animals/d/denebola_brachycephala/ |archivedate=2012-08-20 |df= }} 3. ^{{cite book|url= https://books.google.com/books?id=2rkHQpToi9sC&pg=PA214&lpg=PA214&dq=Denebola+brachycephala&source=bl&ots=hCmuNz2drt&sig=wWMlHMFjGozCGenxf06Ly0rQLtM&hl=es&ei=voNVTNehI4P48AbxpK2PBA&sa=X&oi=book_result&ct=result&resnum=10&ved=0CDwQ6AEwCTgK#v=onepage&q=Denebola%20brachycephala&f=false|author1=William F.
