I can see his point about the body depth, but what is the problem with a fluke-like tail? What falsifies the results of the Platecarpus study?

What's the problem with body depth? I thought that mosasaurs were serpentine/gracile isn't so true anymore.

Welcome to the forum! Actually we are fairly certain that it is an alligatoroid, the discrepancy between the estimates is a little more complex than using crocs or alligators. Schwimmer (2002) uses crocodiles as reference, that we know but Erickson and Brochu (1999) don't say anything about how they made their estimates, Schwimmer speculates they used similar equations to the ones he used but smaller specimens. The most recent estimates come Farlow et al. (2005) which Erickson et al. (2012) references, 3.5 tonnes does seem low and they are aware of that. Thanks. Indeed, having re-read Schwimmer chapter on Deinosuchus size, I've realized its 8.5 tons body mass estimate fits a "12 meter porosus". If one uses the Woodward formula for alligators, the same animal would weigh more than 11 metric tons. BTW, what do you think about this replica? I would say its disproportionate... www.johncox.net/theme-parks/sydney-wildlife-world/ |

Yup, that thing appears to have an skull at least 2m long, way too big, otherwise it seems fairly good.

Appears to be basically even among our two underwater friends.

I'll give this to Deinosuchus, it's much bigger and that'll help it
