How did a 6-year-old boy discover a rare marine fossil
asserted
boy → discover → fossil
According to People, Leo was at a Rafting and Rocks event at Schramm Park State Recreation Area when he spotted a large rock and decided to turn it over.
uncertain
he → accord → it
Outdoor Nebraska states that he hoped to find a crinoid fossil.
asserted
he → state → fossil
Leo noticed an unusual pattern on the underside of the rock.
asserted
Leo → notice → rock
It reminded him of the scales on a garter snake's belly.
asserted
It → remind → belly
He showed it to Kelly Ekue, an outdoor education specialist at the nearby Schramm Education Centre, who immediately noticed something different about it.

who → show → it
What did experts discover about the rare marine fossil
Ekue has led programmes at the outcrop for over seven years, and there are six main types of fossils found there.
asserted
Ekue → discover → fossils
She told Outdoor Nebraska that the fossil looked unlike any of the species she has seen.
asserted
she → tell → species
The imprint was larger than the fossils typically found at the park.
asserted
imprint → find → park
It also appeared almost fish-like, even though the rocks there contain fossils of marine invertebrates rather than fish.
asserted
rocks → appear → fish
Ekue was unsure what Leo had uncovered, so she emailed a photograph to a geologist, who shared it with other experts.
asserted
who → uncover → experts
People named two of them: Shane Tucker, a palaeontologist at the University of Nebraska State Museum, and the geologist Bob Diffendal.

Why are conulariid fossils dating back 200 million to 500 million years so rare
Conulariids lived in what is now Nebraska, as well as other parts of the world, between approximately 200 million and 500 million years ago.
asserted
what → date → world
Their fossils are especially rare because the creatures had soft bodies and thin skeletons that typically broke apart before they could be preserved.
uncertain
they → have → bodies
Researchers identified Leo's specimen by its distinctive herringbone-shaped pattern, which had left an imprint in the limestone.
asserted
which → identify → limestone
According to Outdoor Nebraska, the only other known conulariid fossils found in the state were discovered more than 55 years ago in Louisville and Weeping Water.
uncertain

How will the rare marine fossil help educate visitors
The discovery was exciting for Leo for another reason.
asserted
discovery → help → reason
He had never found a complete fossil before, especially one so large.
asserted
He → find → fossil
He also recalled being told that his find was "rarer to find than a mammoth bone."
asserted
find → recall → bone
Ekue said it was amazing that, among all the rocks in the Schramm outcrop, Leo picked up this one, recognised it as a fossil and thought to ask about it.
asserted
Leo → say → it
Leo will not be taking the fossil home, and he does not mind.
asserted
he → take → fossil
It will remain at Schramm, where staff plan to use it in educational programmes.
