Pennichnus formosae-Homes of Ancient Bobbit Worm

By Yu Yen Pan

In 2013, mysterious, giant, L-shaped burrows were discovered within 20-million-year old strata on the northeast coast of Taiwan. These peculiar burrows astonished a group of experienced ichnologists because no one has seen this trace fossil before!
After a 3-year investigation (with numerous fieldwork and lab), an international research team finally concluded that these burrows were homes of GIANT, AMBUSH, PREDATORY WORMS!!!
So if you have questions like

"What does this trace fossil look like?"
"Who was the trace maker?"
" What kind of behaviour led to this weird morphology?"
