I was talking to a friend of mine about big prehistoric things, and Leedsicthys came up. Now I'm wondering, do we know of any other giant marine filter feeders that lived in the Mesozoic? The only one I know of is Leedsicthys, but there had to have been more.

The plesiosaur Termonotator(Hope I spelled it correct ) is believed to be a filter feeder.

Maybe those gigantic ichtyosaurs, like Shonisaurus and such, were filter feeders... Weren't they toothless?

Teeth or baleen are required for filter feeding otherwise what are you filtering the water through? I guess Pterodaustro doesn't count as giant huh? |

The following abstract kind of sums it up. www.sciencemag.org/content/327/5968/990.abstractI do not believe there were any mesozoic marine reptiles that were filter feeders, but I am primarily familiar with ichthyosaurs. There is some good evidence that Shastasaurus was a suction feeder, but not a filter feeder. Shonisaurus has been listed as toothless based on a huge ichthyosaur from British Columbia, but that always has been a problem as Shonisaurus popularis definitely had teeth. There was a chapter in the book Ancient Marine Reptiles about why marine reptiles were no suspension feeders, but I am not sure its premise is still valid. |

What about Pterodaustro? They had teeth like long needles that looked a lot like baleens. So, to me, they obviously were filter feeders. And they lived during the Mesosoic.
