What is true about the climate during the Paleocene epoch?

The Paleocene epoch, which spanned from about 66 to 56 million years ago, is characterized by a climate that was generally hot and humid. During this time, global temperatures were significantly higher than today, and the climate was conducive to the flourishing of lush forests and a diverse range of plant and animal life. This warm and moist environment allowed tropical and subtropical conditions to dominate, facilitating the recovery and diversification of many species following the extinction event that marked the end of the Cretaceous period.

The abundant vegetation and favorable growing conditions supported a variety of mammals and birds, which began to evolve substantially during this epoch. In contrast to cooler or arid conditions, the warm and humid climate of the Paleocene played a critical role in shaping the ecosystems of that era, paving the way for future evolutionary developments in the Cenozoic Era.
