The Trendy Regaliceratops  by Celia Berrell

This leafy-loving herbivore

weighed a hefty ton or more.

Six metres long and bulky strong,

this dinosaur, we got so wrong!

 

His bony frill’s not meant as armour.

More, a snazzy lady-charmer!

Pretty as a peacock’s tail

in battle, it would surely fail.

 

Those horns above his nose and eyes

are such a trendy cute surprise.

Too flimsy for a fight to start

his fancy horns are body art!

 

A cousin of Triceratops

with colourful Canadian chops,

perhaps he was polite and coy

although he looked more like HELLBOY!

Spiky-Headed Dino Discovered

Dubbed “Hellboy,” the triceratops relative sports a bevy of horns on its crested cranium.

An artist’s impression of Regaliceratops peterhewsiIMAGE: JULIUS T. CSOTONYI/ROYAL TYRRELL MUSEUMResearchers have unearthed an impressive dinosaur skull from a Canadian river bed. Officially calledRegaliceratops peterhewsi, the new species had numerous protuberances jutting from its head, including a couple that reminded its discoverers of a certain comic book character. “There are these really stubby horns over the eyes that match up with the comic book character Hellboy,” study leader Caleb Brown, a paleontologist at the Royal Tyrrell Museum of Palaeontology in Alberta, Canada, told National Geographic. Brown and his colleague Donald Henderson published a report of the find last week (June 4) in Current Biology.

According to Brown and Henderson, R. peterhewsi—which was named after Peter Hews, the oil-and-gas geologist and amateur fossil hunter who discovered the specimen near the Oldman River in Alberta in 2005—roamed prehistoric North America about 70 million years ago. “This discovery shows that we are perhaps still quite a ways from knowing the complete diversity of dinosaur species in the Late Cretaceous of western North America,” James Farlow, a geologist at Indiana University–Purdue University Fort Wayne, told Smithsonian. “The evolutionary tree presented by the authors suggests that an immediate ancestor ofRegaliceratops that would have lived a few million years ago has yet to be found. So there are plenty of interesting dinosaurs still to be discovered.”

  1. peterhewsi’s bony arsenal, studding its 592-pound skull, was likely used for mating rituals rather than aggression or defense, according to Brown. “When the first horned dinosaurs were found . . . we thought these were probably used for defense,” Brown told theCalgary Herald. “You have these iconic images ofTriceratopsdoing battle with Tyrannosaurus rex. [But] the more horned dinosaurs that we find, the less the explanation of defense makes sense. There are a number of species where their horns would be pretty much useless in defense.”

The newly analyzed fossils also suggest that there are more horned dinosaurs to be discovered. “This find tells us more about the kinds of horned dinosaurs that lived just before Triceratops was on the scene,” Andrew Farke, a curator at the Raymond M. Alf Museum of Paleontology, told Smithsonian. “I am now really curious to see what other oddities might have been around at the same time—this new beast is an important data point.”

“Baby Eucalypts” with Teacher Notes  by Celia Berrell

Baby Eucalypts

 

When fire has passed,

eucalypts are reborn.

Tough woody capsules

release their seeds,

falling on ash

which is nutrient-rich.

Plunging their roots

into first-rained earth,

their view of the Sun

helps speed that growth,

for the canopy’s shade

is burnt and gone.

 

Animals fled.

So new leaves, uneaten,

make a dash

towards the sky.

No insects in sight

means delicate shoots

don’t get sucked dry

of their life-giving juice.

Alone in the quiet

on black-rich soil,

those baby trees have

the best start in life.

Fire has been a constant visitor to Tasmanian forests for millions of years. It has shaped the evolution of many plant species and communities. In fact, many species are not only adapted to fire, but actually have features that help to promote it. Fire is an essential part of the life cycle of many plant communities, including dry eucalypt forests and wet eucalypt forests. Fire behaves differently, however, in each of these systems. A key difference between eucalypts and rainforest trees is that eucalypts are adapted to, and take advantage of major, widespread disturbances of the forest canopy, especially those caused by fire. Individual trees of different species can withstand the effects of fire to varying degrees, but all eucalypt forest types depend on it to some extent for regeneration. Eucalypt seed release is triggered by fire, when tough, woody capsules empty their contents onto a nutrient-rich ash seedbed from which all the understorey competition for light, water and nutrients has been removed. Browsing animals are driven out for a time, and the heat-treatment of soil reduces the numbers of plant-eating insects and soil organisms during the short but crucial early growth period.
