Not really though — from NPS:

The hottest air temperature ever recorded in Death Valley (Furnace Creek) was 134°F (57°C) on July 10, 1913. During the heat wave that peaked with that record, five consecutive days reached 129° F (54°C) or above.

I think the dinosaur moment would be more of a global phenomenon, e.g., rising ocean temperature. My understanding is that Death Valley is obscenely hot with or without humans. The rising ocean temperature and melting ice caps, on the other hand…🦖🌎💥
