What did Phil Heckel do? Fossil diversity reside in the marine environment Vertebrates are not present Fossil diversity taper off in the hypersaline end and the brackish water conditions Blue green algae, gastropod -> wide living environment Salinity plot Tends to stop at subtidal and intertidal, not many organisms migrate into the intertidal zone; if they do, organisms are most likely burrowing organisms or they have members in the freshwater environment Most get into slope area or even trenches Conclusion: Because we are in an ice house condition, oxygen is circulated by a down current; therefore, water depth is not restrictive. During warm water times, the fate of the organisms are unknown. Water depth plot Hard v. firm v. soft v. mobile Few organisms do well in soft soupy substrate; so very few organisms do well In major deltas; few echinoids and gastropods Mobile environments get compacted through time; so the less rapid deposition there is, the more compact it will get over time, the more organisms you will find
