Your topic, focusing on the St. Johns pottery in Florida, appears to be quite specific and niche. I'd suggest diving into the works of archaeologists and anthropologists specialising in Southeastern U.S. archaeology, particularly those focusing on Florida and pottery analysis. While I don't have the capability to search real-time databases, I can provide you with some general recommendations to guide your research. However, for the most updated and specific resources, you would need to use academic databases like JSTOR, Google Scholar, and others for your search.

Specific papers/books to consider:

For the analysis of pottery sherds and temper components:

As the study of spiculae sponge resources in the context of pottery temper seems to be a quite specific and niche topic, finding resources that address this topic directly might be challenging. You might need to delve into the broader literature on using organic materials as pottery temper, then apply those principles to the specific case of spiculae sponge resources in Florida.

Remember to check the references and citations of these sources for more potentially useful resources. You might also want to contact archaeologists who are currently active in the field – they could point you towards recent publications or ongoing research that hasn't been published yet.

The suggestions provided above should give you a good starting point for your research. However, to access the latest research papers, I recommend utilizing academic databases and scholarly search engines, and if possible, reaching out to libraries or universities that may have subscriptions to these platforms.

Thank you Joshua,I will do search your suggested authors. I have done already a compilation of some of them that you named. I appreciate your help.
