Step 1: Define terms.
- Biostratinomy: Study of processes that occur between death of an organism and its burial in sediments (transport, decay, disarticulation, scavenging).
- Biostratigraphy: Use of fossils for correlation and relative dating of rock strata.
- Taphonomy: Broader study of fossilization processes, including both biostratinomy and diagenesis after burial.
- Taxonomy: Classification of organisms.
Step 2: Apply definition.
Since the question specifically asks for processes from death to burial, this is strictly the domain of Biostratinomy.
Final Answer:
\[
\boxed{\text{Biostratinomy}}
\]
