Understanding Dickinsonia and the Ediacaran Period

In 2015, Ilya Bobrovskiy embarked on a project to uncover the mysteries of Dickinsonia, a key organism from the Ediacaran Period. His innovative approach involved molecular analysis of fossilized fat, revealing Dickinsonia as an animal. This research sheds light on the environmental changes that led to the diversity of life forms before the Cambrian Explosion. Despite these findings, many questions about the Ediacaran organisms remain unanswered, prompting further research into their extinction and ecological roles.

What was the main goal of Ilya Bobrovskiy's project?

• To classify all Ediacaran organisms

• To prove Dickinsonia was a plant

• To revolutionize the understanding of early complex life

• To find new fossil sites

What was one of the main challenges in classifying Dickinsonia?

• Its fossil location

• Its color

• Its bilateral symmetry

• Its size

What is the 'Death Mask' hypothesis related to?

• The preservation of soft-bodied organisms

• The color of fossils

• The size of Dickinsonia

• The location of fossil sites

What did Bobrovskiy use to identify Dickinsonia as an animal?

• Steroid molecules

• Fossil size
