The spiniest seeds found in Mid-Cretaceous Myanmar amber.

ABSTRACT: Although angiosperms occurred earlier, their radiation did not occur until the Middle Cretaceous. Owing to a lack of knowledge of early angiosperms, this radiation used to be mistaken for the origin of angiosperms and became Darwin's "abominable mystery". Palaeobotanical progresses in recent decades have released more information on early angiosperms, especially their Middle Cretaceous radiation. The fossil angiosperms from Myanmar amber shed unique light on the evolution and diversity of angiosperms due to their exquisite preservation. To enhance our understanding of this fossil lägerstatte, here we report a new fossil angiosperm named Spinograna myanmarensis gen. et sp. nov. from Myanmar amber. The fossil is a fruit bearing spiny seeds. Its seeds are unique in morphology: they are discoi
