Continuing work on the paleontology and sedimentology of the Jehol Group (Lower Cretaceous, China) is yielding numerous new insights into the evolution of many Mesozoic plant and animal clades. Nevertheless, many questions remain unanswered regarding Jehol paleoenvironments, paleobiology and paleobiogeography. All of this information will be crucial in providing a detailed reconstruction of this extinct ecosystem.
对热河生物群（中国下白垩统）古生物学和沉积学的持续研究，正在为许多中生代动植物类群的演化带来众多新见解。然而，关于热河古环境、古生物学和古生物地理学仍有许多问题未得到解答。所有这些信息对于详细重建这个已灭绝的生态系统至关重要。
