Researchers from Museums Victoria and the University of Melbourne have CT scanned all 13 known Tasmanian tiger joey specimens to create 3D digital models which have allowed them to study their skeletons and internal organs, and reconstruct their growth and development.
Researchers have discovered microfossils resembling fungi in lavas that erupted on the seafloor 2.4 billion years ago, representing the oldest evidence of fungal life.
The new paper, published in Nature Ecology and Evolution today, suggests that fungi not only emerged much earlier than suspected but also evolved beneath the sea rather than on land.
In its transition from rich biodiversity to the barren, cold land of blizzards we see today, Antarctica provides a dramatic case study of how subtle changes in continental positioning can affect living communities, and how rapidly catastrophic changes can come about. Frozen in Time reconstructs Antarctica’s evolving animal and plant communities as accurately as the fossil record permits.
"Doth any man doubt, that if there were taken out of men’s minds, vain opinions, flattering hopes, false valuations, imaginations as one would, and the like, but it would leave the minds, of a number of men, poor shrunken things, full of melancholy and indisposition, and unpleasing to themselves?" Francis Bacon
