Nice, simple explanation and good, clear figures. My only concern is, as a sedimentology professor, the difficulty in unteaching students that a rise in sea level always causes a transgression. I understand the desire and need for simplicity, but this dogma is hard to get out of their heads. In reality, with a sea level rise, we are looking at a balance between how fast that rise occurs and how fast the space is filled with sediment, which could result in either a transgression or a regression, depending upon that balance. Still, good video.
If you think of when you go to the beach, where would you find seashells? Broken pieces would be found towards the sandy beach (think of walking the beach looking for shells). So you could possibly find fragments in sandstone layers. I'd assume that smaller fragments could be found with the finer particles. Fossiliferous limestone can also show sea-shells. Coquina is also a sedimentary rock made of broken sea-shells. So, I'm thinking, based on that, you could potentially find them in most environments. Anywhere a bivalve could have lived, or its shells could have washed up.
ok that makes a lot of sense actually. I'm not sure why it stumped me. I'm doing an experiment about regression and using plaster to "lithify" clay, sand and gravel. science makes me OVERthink a little, thanks!

never get a clearer picture on this before i watch this. Good job! Thanx a lot
This is pretty awesome. Just randomly thinking about this today.
Thanks Patrick Baldwin, this explanation helped me a lot. All the best.
Thanks Alot .. because I am studying Geology And it's so Difficult
OMG Thank you sooo much i finally understand. Geology test tomorrow. ;-;
thank you very much mr baldwin!
First Birthday greetings
Second Thank you for this video !!
God bless you
Best wishes from Rajesh Madan
No worries! Glad it helped!
thanks for the knowledge.. simple and easy to understand...
was it really this simple..? wow, thank you so much (:
Thank you so much! Really, reaaally useful! :)
Well done. This is very helpful.
@Patrick Baldwin thanks for saving my ass from failing
great, Brief and helpful
Thanks
what layer would we most likely see shells? would it be in the calcite layer with the coral?
