Questions for Further Thought
- How could the fact that the Buffalo Canyon flora grew around a lake influence the way one might interpret climatic conditions with both the Nearest Living Relative approach and leaf margin analysis performed in this lab?
- How would you address the apparent discrepancy between the climatic preferences of extant Quercus chrysolepis and Zelkova? What about the not insignificant proportion of conifers in the Buffalo Canyon flora?
- What overall trend do you observe through time in Western North America based on the floras you have to work with in this lab?
- Is there a role of geography in this pattern? Consult the map in 3003 VLSB. The location of each fossil flora is marked with a small flag.
