We can learn unimaginable amount of things bout the history of life, climate, geosystems and the processes of evolution from the fossil record. But we need strong database curation and financing infrastructure.

Sea dragon in the jaws of a fish:
"Finding embedded teeth, while rare, removes this ambiguity. Here we describe a tooth embedded in a mid-cervical vertebra of a subadult plesiosaur, Polycotylus latipinnis"

"Stem tetrapod" from the Early Permian. You can think about it as a "living fossil" holdover from the earliest Carboniferous. But as Jason and others explain it was specialized in its dentition, completely weird and possibly was herbivorous! A mixture of primitive and derived in unusual direction.

The extreme unevenness in the completeness of the stratigraphic, and by implication fossil, record is formed by many processes. Apparently the most profound gap— the Great Unconformity, is driven by tectonics.

These kinds of studies are extremely important in deciphering from the mechanistic point-of-view the evolution of behaviors using time-calibrated trace fossil record.

"We describe the only known example of a three-dimensionally mineralized heart, thick-walled stomach, and bilobed liver from arthrodire placoderms, stem gnathostomes from the Late Devonian Gogo Formation in Western Australia"

A very interesting article on the Bretskyan hierarchy mechanisms of the divergence in fishes:
"...gaps, such as the Sinaloan, Central American, and Galápagos breaks, consistently restricted gene flow"
