âThe Cambrian explosion was a time of unique morphologic experimentation in the history of life. Numerous marine invertebrate phyla and classes, including many extinct groups, appeared abruptly in the
You form the tower by fitting the remaining girders together to form a long tube. Insert the end of one girder into the end of another one and push them together until the tape prevents you from pushing them any farther. This gives you a single tube that is somewhere between 40 and 60 ...
Today we are experiencing a modern-day Cambrian explosion in artificial intelligence (AI). It seems as though a new, mind-boggling tool becomes available every week. Initially, the generative-AI revolution was driven by large language models like ChatGPT, which imitate humans' verbal intelligence....
Paleontologist Michael Habib, one of the paper's co-authors, suspected that the "Quetzalcoatlus" fossil was not quite what it seemed when he saw it for the first time several years ago. With the help of David Hone, a pterosaur taxonomy specialist, the two realized that the 30-year-old sp...

The Cambrian Explosion and Fossil Records (541 – 245 million years ago) TheCambrian explosion was the largest diversification of lifein Earth’s history. Everything before this era was Precambrian. We couldn’t identify life because we didn’t havefossilized shells or animals. This is when hard...

The Proterozoic Era was a time period in Earth’s geologic history that spanned from about 542 to 2500 million years ago. It was a long era with numerous changes to the Earth’s system like multicellular life. The Proterozoic Era was a pivotal phase in Earth’s history marked by the emer...
These complex multicellular creatures were the first animals, and they were a major success. Soon afterward, roughly 540 million years ago, animal life erupted, diversifying into a kaleidoscope of forms in what’s known as the Cambrian explosion. Prototypes for every animal body plan rapidly ...
Soft tissue rarely gets preserved in the fossil record, which is one reason why locations like the Burgess Shale, which contains fossils of soft-bodied animals from the Cambrian explosion some 545 million years ago, are so important. In 2023, a study published inPapers in Paleontologyrevealed th...
