I intend this thread to be a debate thread between atheists and Christians who don't adhere to biblical literalism against YECS so I request restraint in moderation
That said
I believe in a world wide flood for the following reasons
Latest archeological evidence from marine deposits show most of Africa was under water https://www.researchgate.net/publication/318244551_Major_transgression_during_Late_Cretaceous_constrained_by_basin_sediments_in_northern_Africa_implication_for_global_rise_in_sea_level
They found 36 ankylosaurs fossils in Alberta of which 26 were floating upside down. To me the large numbers suggest a flood event rather than successive bloat and float events Also ankylosaur fossils are found all over the world and typically in marine deposits according to both the video and the article suggesting death by flooding. There is also computer modeling suggesting a preference for floating right side up according to the article - however, I am reluctant to trust computer modeling.
I realize this is a creationist source which I try to avoid in favor of academic source, but the 3 points I make here are all backed up by academic papers linked in the post

3. there seems to be reports of dinosaurs found mixed with marine fossils repeatedly in the late cretaceous (ie the time when dinosaurs went extinct.
One good example of this is hell creek
The mixing seems to have caught on with mainstream scientists who are saying a meteor impact caused a worldwide tsunami.

A quick glance at the hells creek Wikipedia page says that along with fish, they also found sharks, octopuses, sea turtles and marine reptiles like the mosasaur.
I'm not the only one surprised by salt and freshwater species with land mammals being found at hells creek. Here is a non-creation scientist saying that they are perplexed by the finding in the New Yorker

Now here is a research paper from Berkley saying that freshwater and marine and terrestrial animals together all dead at the same time can best be attributed to a tsunami (ie. what I call a flood)
