Mysterious gap in evolutionary transition

"A 15-million-year gap in the tetrapod fossil record, called Romer's Gap, made that classic tale more of an estimation than something set in stone - until now.
An interdisciplinary team of paleontologists, geologists, and other specialists describe five new tetrapod species from fossils dating within just that gap, from about 360 million to 345 million years ago, in a paper published Monday in the journal Nature Ecology & Evolution. And these new fossils are already revealing insights into the deep evolutionary history of life on Earth."
