Title: The Smallest Known Tetrapod Footprints: Batrachichnus Salamandroides from the Carboniferous of Joggins, Nova Scotia, Canada
Authors: Matt Stimson, Spencer G. Lucas, and Gloria Melanson

A new specimen of Batrachichnus salamandroides from the classic Carboniferous section at Joggins, Nova Scotia, is the smallest set of tetrapod footprints known in the fossil record. The trackmaker was a juvenile, quadrupedal temnospondyl or microsaur with a trunk length of 3.55 mm and an estimated body length of 8 mm (skull, presacral vertebrae, and caudal vertebrae). The 48 mm-long trackway preserves a high degree of extramorphological variation along its course, including a gait change associated with a change in direction along with an increased stride and pace, and the appearance of overstepped imprints, in the latter portion of the trackway. These morphological changes suggest the tetrapod changed from a walking gait to a running gait.

Likely footprint of spiky dinosaur in NASA's Md. campus

Dinosaur tracker Ray Stanford is convinced, a low-slung armoured beast roamed what is now a NASA campus in Greenbelt, stamping a huge footprint that went unnoticed until he spied it this summer.
A scalloped mini-crater with four pointy toe prints pressed into ruddy rock, the putative dinosaur track juts out from a scruffy slope at NASA's Goddard Space Flight Center, home to 7,000 scientists, engineers and other workers with their eyes firmly turned skyward.

Dinosaur footprints discovered in Beijing

Paleontologists say several hundred fossilized footprints in a Beijing suburb are those of dinosaurs. The footprints, unearthed in a geological park in Yanqing county, are the first dinosaur traces the city has found, according to Zhang Jianping, researcher at the China University of Geosciences.
They were left by dinosaurs that lived some 140 to 150 million years ago in the late Jurassic period, said Zhang.

Large Field of Dinosaur Tracks Uncovered in Southwest Arkansas

The discovery of a large field of dinosaur tracks in Arkansas has researchers busy using cutting-edge technology and traditional techniques to learn all that they can about the animals and environment that existed there 120 million years ago.
The track site, found in southwest Arkansas, covers an area of about two football fields and contains the fossilised tracks of several species and tracks from multiple animals of the same species, some of which have never been previously documented in Arkansas. The site will help researchers learn not only about the creatures that once roamed through the area, but also about the climate during the Early Cretaceous period 115 to 120 million years ago.

Protoceratops Dinosaur found with its own tracks

A recent examination of the 80-million-year-old specimen revealed a single footprint preserved in the rocks encasing the fossilised bones.
Polish and Mongolian fossil hunters first unearthed it in 1965 in Mongolia.
Scientists now report the results of its re-examination in the journal Cretaceous Research.
The dinosaur is a Protoceratops, and since this is one of the most common dinosaurs found in the rich fossil beds of the Gobi Desert, it was not deemed to be very significant. But the scientists say it is the first example of a dinosaur being preserved with its own footprints.

Sometime between 145 million and 140 million years ago, in the vicinity of what is now Teruel, Spain, a small herd of sauropod dinosaurs travelled together near a shallow, sandy bay. We know this because they left their footprints in the rock record, and paleontologist Diego Castanera and colleagues have just released an in-press report about these significant trackways in Palaeogeography, Palaeoclimatology, Palaeoecology.

Sussex fossil collector finds 'smallest' dinosaur

The fossil of what is thought to be one of the world's smallest dinosaurs has been found at a brickworks in Sussex.
Experts from the University of Portsmouth identified the creature after a local fossil collector found it at the Ashdown Brickworks near Bexhill.

New Dinosaur May Be World's Smallest

A new species of carnivorous non-avian dinosaur, described in the latest issue of Cretaceous Research, could be the worlds smallest known dinosaur.
The tiny dinosaur, dubbed the "Ashdown maniraptoran," measures about a foot in length and was unearthed in the United Kingdom. It lived during the Lower Cretaceous, a period lasting from 145 to 100 million years ago.

A boulder with three different fossilised dinosaur footprints has been found on an Isle of Wight beach.
It provides evidence about life around Brook Bay 130 million years ago.
Palaeontologist Dr Steve Sweetman found the 50kg rock containing prints of an adult iguanodon, a theropod and a baby iguanodon-like dinosaur.

Gas plant on the Dampier Peninsula coast may destroy dinosaur footprints

The world's longest chain of dinosaur footprints would be broken by a new gas processing plant and port planned for the West Australian coast, scientists say.
The fossilised footprints of 15 types of dinosaur, including diplodocus, brachiosaurus, muttaburrasaurus and several types of large carnivore stretch for 80 kilometres along the Kimberley coast around Broome.
They were made when the dinosaurs strode across mudflats about 130 million years ago, but some of the footprints could be gone forever within a few years if the port goes ahead.
