A bizarre group of uniquely shaped organisms known as rangeomorphs may have been some of the earliest animals to appear on Earth, uniquely suited to ocean conditions 575 million years ago. A new model ...

Rangeomorphs, fern-like animals from the Ediacaran period, were distinguished, to say the least. In their hey day, these early lifeforms colonized entire sea floors and grew up to two meters tall.

The earliest example of reproduction in a complex organism has been discovered in a 565 million-year-old rangeomorph fossil by University of Cambridge researchers. Rangeomorphs are considered to be ...

This is a paleontological reconstruction of rangeomorph fronds from the Ediacaran Period (635-541 million years ago). These species are from the deep-marine Avalon Assemblage (approximately 575-560 ...

Here we propose and test the hypothesis that rangeomorph growth was nutrient-dependent due to feedbacks between branch volume, relative surface area and nutrient uptake. This provides a developmental ...
