Footprints of Cretaceous Dinosaur Found at NASA’s Goddard Space Flight Center

(Aug. 21, 2012) — About 110 million light years away, the bright, barred spiral galaxy NGC 3259 was just forming stars in dark bands of dust and gas. Here on the part of the Earth where NASA’s Goddard Space Flight Center would eventually be built, a plant-eating dinosaur sensed predators nearby and quickened its pace, leaving a deep imprint in the Cretaceous mud.

On Friday, Aug. 17, 2012, noted dinosaur hunter Ray Stanford shared the location of that footprint with Goddard’s facility management and the Washington Post newspaper.

“This was a large, armored dinosaur,” Stanford said. “Think of it as a four-footed tank. It was quite heavy, there’s a quite a ridge or push-up here. … Subsequently the sand was bound together by iron-oxide or hematite, so it gave us a nice preservation, almost like concrete.”

Stanford, a “proud amateur dinosaur tracker” has had several papers published, including the discovery of a new species of nodosaur from a fossilized hatchling found near the University of Maryland in College Park. He previously confirmed the authenticity of this track with David Weishampel of Johns Hopkins University in Baltimore, author of the book “Dinosaurs of the East Coast.”

He had material from the same Cretaceous-era sedimentary rock dated, with help from the US Geological Survey, to approximately 110- to 112-million years old, by analyzing pollen grains sealed in the stone. The Cretaceous Period ran between 145.5 and 65.5 million years ago, and was the last period of the Mesozoic Era.

Goddard Facilities Manager Alan Binstock said the agency considers the footprint and its location “sensitive but unclassified.”

The footprint is on federal land, so improperly removing it could potentially violate three laws: the Antiquities Act, the Archaeological Resources Protection Act and the Paleontological Resources Preservation Act.

NASA officials will next consult with the State of Maryland and paleontologists to form a plan for documenting and preserving the find, Binstock said.

Stanford also identified and presented several smaller footprints — three-toed, flesh-eating therapods [sic; theropods] — to Goddard officials from the same site.

He called the location of the find “poetic.”

“Space scientists may walk along here, and they’re walking exactly where this big, bungling heavy armored dinosaur walked, maybe 110 to 112-million years ago,” Stanford said.

Feb. 5, 2013 — A grouping of 110 to 112 million-year-old dinosaur footprints pressed into mud from the Cretaceous Period have now been safely moved from their original setting on the grounds of NASA’s Goddard Space Flight Center in Greenbelt, Md. Until further scientific study is possible, the footprints, now wrapped in protective material, will be stored on the Goddard campus: here.

Rare baby whale born in New Zealand harbour


This video is called Breeding Southern Right Whales – Attenborough – Life of Mammals.

From the New Zealand Herald:

Rare right whale spotted in Auckland harbour

6:48 PM Tuesday Aug 21, 2012

A rare southern right whale gave birth this morning off Auckland’s Browns Bay.

AUT University Marine Researcher Emma Beatson says the whales are a nationally endangered species and heavily exploited by whalers.

She says they’re slowly recovering, but not a lot is known about them.

Ms Beatson says they generally breed around Auckland Islands at this time of year, but it’s very rare to see one coming into shallow waters to calve.

Fireflies, evolution’s Johnny-come-latelies


This video about marine life is called Amazing and weird creatures exhibit bioluminescence – Blue Planet – BBC Earth.

From New Scientist:

Glowing insects evolved surprisingly recently

14:40 21 August 2012 by Karl Gruber

Fireflies, one of the most conspicuous of nocturnal insects, are a relatively recent addition to the twilight world. A new analysis of all bioluminescent species suggests that those living on land might be mere tens of millions of years old – a fraction of the age of bioluminescing marine groups.

Bioluminescence serves many purposes, from communication to finding mates, scaring off predators to attracting prey. Yet while many marine species bioluminesce, very few terrestrial animals have evolved the ability. Besides fireflies and a few other insects, only one snail, a few earthworms and a handful of millipedes can produce light.

To better understand this striking difference between land and sea Peter Vršanský, a palaeobiologist at the Slovak Academy of Sciences in Bratislava, and his colleagues, studied the evolutionary history of all known marine and terrestrial groups of bioluminescent species.

Their results show that most marine light-producing animals can trace their origins back to the Devonian period, at least 400 million years ago. Bioluminescent landlubbers are all much younger – no more than 65 million years old.

“There are unexpected, but very important indications for a modern origin of luminescence on land,” says Vršanský.

It’s possible that luminescent species appeared on land only when night life began to diversify, says Vršanský – although there are indications that some of the dinosaurs and early birds living before the bioluminescent insects evolved were nocturnal.

Another possibility is that terrestrial species have only recently cracked the problem of disposing of the toxic by-products of bioluminescence – less of an issue in the marine realm where temperatures are often cooler and more stable than in tropical forests.

Whatever the reason for the discrepancy, the future for terrestrial bioluminescent species might not be bright, says Vršanský. “While bioluminescent insects have diversified into 13 known species, most of them are known from a single collected individual,” he says. “That suggests they are extremely rare and vulnerable to extinction.”

That includes new species that are only just being described by science. Vršanský’s analysis, for example, took in a new species of bioluminescent cockroach his team has named Lucihormetica luckae. Uniquely, it produces light on its body in the same pattern and at the same frequency as the click beetle (Pyrophorus). Because Pyrophorus is toxic – and Lucihormetica luckae is not – it seems likely that the cockroach is the first known species to use bioluminescence to mimic another species for defence purposes.

Dutch rare birds, new Internet site


This video is called Birds of Holland in the Spring – PIJNACKER – The Netherlands.

The Dutch SOVON ornithologists report that on Saturday 25 August a new Internet site will start.

This site, made by Dutch Birding, called Digitale Avifauna, will have data on rare birds in the Netherlands ever since 1800 which up to now have only been accessible on paper.
