| contents | White shark comparison reveals a slender body for the extinct megatooth shark, (Lamniformes: Otodontidae). Sternes, Phillip C Jambura, Patrick L Türtscher, Julia Kriwet, Jürgen Siversson, Mikael Feichtinger, Iris Naylor, Gavin J P Summers, Adam P Maisey, John G Tomita, Taketeru Moyer, Joshua K Higham, Timothy E da Silva, João Paulo C B Bornatowski, Hugo Long, Douglas J Perez, Victor J Collareta, Alberto Underwood, Charlie Ward, David J Vullo, Romain González-Barba, Gerardo Maisch, Harry M Griffiths, Michael L Becker, Martin A Wood, Jake J Shimada, Kenshu The megatooth shark, †, which likely reached at least 15 m in total length, is an iconic extinct shark represented primarily by its gigantic teeth in the Neogene fossil record. As one of the largest marine carnivores to ever exist, understanding the biology, evolution, and extinction of † is important because it had a significant impact on the ecology and evolution of marine ecosystems that shaped the present-day oceans. Some attempts inferring the body form of † have been carried out, but they are all speculative due to the lack of any complete skeleton. Here we highlight the fact that the previous total body length estimated from vertebral diameters of the extant white shark for an † individual represented by an incomplete vertebral column is much shorter than the sum of anteroposterior lengths of those fossil vertebrae. This factual evidence indicates that † had an elongated body relative to the body of the modern white shark. Although its exact body form remains unknown, this proposition represents the most parsimonious empirical evidence, which is a significant step towards deciphering the body form of †. |
