As per the paleontologists, the anchored tubular structures of fossilized Funisia dorothea showed dense clusters which are believed to be formed by mating of floating egg and sperms in the water. Also traces have been found that states asexual mode of reproduction through budding where buds were formed in the same way as that of coral, sponges etc and then these buds grew into full sized Funisia dorothea. Thus, the fossil species have the complex ability to produce both sexually and asexually.
Scientists use similarities between organisms to connect them. The similarities and contrasts between fossils discovered in sedimentary rock and living species can be compared.
