Here's a new paleo-reconstuction I drew since the past two days of Albicetus oxymycterus, which is a mid-Miocene raptorial physeteroid none of you have probably heard about. Special thing between this little Moby-Dick and city I live in is that although it was not discovered directly in PV, it was discovered very nearby in Santa Barbara in the same formation and sublayer that exists here which highly suggests that it also swam here 16-14 million years ago. I tried to make this as scientifically accurate as possible using the resources I had, which included the entire 2015 paper establishing the genus Albicetus. I mainly used a pre-existing sketch of Aulophyseter morricei as body reference (which the paper stated is morphologically most similar to A. oxymycterus except for dentition) and used the paper's skull reconstruction for the head. I used a Zygophyseter-like head as the paper stated that the supracranial basin of the skull does not elongate to the end of the maxilla like that of Zygophyseter and Acrophyseter, which both posses snouts as a result. For the body size, I calculated the skull-body ratio by dividing the mean and lower condylobasal length estimates to the total calculated length, which came with either a 1:4.6 or 1:4.9 ratio. (Unrelated to the drawing, the 1:4-5 ratio is based on using a body formula for Physeter and Kogia spp.. If you use the upper Livyatan melvillei /Zygophyseter varolai estimates as reference, a ratio of 1:5.9 and total length of 8.6 meters is calculated) I don't know any of the advanced formulas some of you guys probably do know about and simply used division, so my calculations might not be the most accurate ones. I also put in a diver for scale this time! EXTRAS
