I want to know the answer to the following question:
What type of animals took longer to reestablish?
All the background I'm provided with is that "Recent research indicates that the specialized animals that formed complex ecosystems, with high biodiversity, complex food webs and a variety of niches, took much longer to reestablish, recovery did not begin until the start of the mid-Triassic, 4M to 6M years after the extinction and was not complete until 30M years after the Permian–Triassic extinction event.". Is that enough to answer the question?
Answer: yes
