There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
Based on this new evidence, it seems that a Otodus/Carcharocles megalodon was at a maximum of 15 meters, which will equal to a great white of 6 meters, in absolute dimentions. Above that will be quite exceptional. However we must remember that the whales of those days were also comparative small. The maximum size of the whales killed by O/C megalodon, like Cetotherimum, were about 10 meters long. Even the orcas of those days were relatively small, been of about 4-5 meters long (similar to the modern false killer whale). I don't think that the orcas will target the largest megalodon sharks but certainly were ready to kill the smaller ones of the size of the current whales of they days, at about 6-10 meters long.
It seams that in the time betweee Miocene and Pliocene, the animals like the baleen whales and even the orcas were much smaller than the modern representatives, so the only real giants, based in the fossil records, were the Otodus/Carcharocles megalodon and the Lyvyatan melvillei, with specimens reaching over 15 meters long.
