Baby dinosaur footprints discovered in Colorado

November, 02 2010

Digital Journal

Infant dinosaur footprints have been discovered in the foothills west of Denver, Colorado, near the town of Morrison.

These tracks were made about 148 million years ago, before the Rocky Mountains rose, when the savanna was full of dinosaurs.

According to Matthew Mossbrucker, director of the Morrison Natural History Museum, who discovered the prints, the fossil tracks represent infant sauropods. Sauropods were giant, herbivorous long-necked dinosaurs, sometimes known as “brontosaurs.” The sauropod Apatosaurus [see also here] was first discovered in Morrison in 1877.

Details of the findings were presented at the 2010 Geologic Society of America Annual Meeting & Exposition in Denver on November 1. Although collected five years ago, these tracks were a part of a backlog of new discoveries made by Museum staff. The tracks are on permanent display at the Morrison Natural History Museum.

Paleontologist Dr Robert T Bakker of the Houston Museum of Natural Sciences (who also serves as the Morrison Museum’s volunteer curator of paleontology) said on the finding, “The latest discovery is a tribute to Director Matt Mossbrucker and his crew of sharp-eyed volunteers. Never before has science given us such an intimate glimpse of baby brontosaurs – a window into Jurassic Family Values.”

The tracks are ovular in shape and can be covered by a coffee mug. This would mean that the infant sauropods were about the size of a small dog. While one animal left average walking footprints, another infant dinosaur ran parallel to adult tracks. The scientists also found an unusual pattern. “The distance between each step is two-times wider than what we observe in walking tracks indicating the animal was at a low speed run,” said Mossbrucker. “I am not aware of any running sauropod tracks anywhere.”

ScienceDaily (Feb. 3, 2011) — Terrain thought to be ruled by only the largest dinosaurs to inhabit Earth could have in fact been home to dozens of other creatures, ground-breaking research from The University of Manchester has found. Writing in the journal of the Royal Society Interface, Dr. Peter Falkingham has discovered that dinosaurs only created lasting footprints if the soil conditions were perfect to do so — and entirely depending on the animal’s weight: here.

  1. Indigenous Dinosaur Named After Korea

    A dinosaur has been named after Korea for the first time in paleontology.

    After seven years of research and restoration efforts, the Korea Dinosaur Research Center at Chonnam National University on Monday unveiled an indigenous dinosaur that lived on the Korean peninsula during the Late Cretaceous period. Koreanosaurus Boseongensis is a Hypsilophodontid, or small ornithopod.

    A team of researchers at university discovered the fossil remains in the Boseong region in May 2003.

    A model of the dinosaur measures 2.4 m in length. Using three-dimensional technology, the center was able to recreate not only the bone structure, but also the teeth, eyes and even skin fragments. It published its findings in the German journal Neues Jahrbuch fuer Geologie und Palontologie. / Nov. 02, 2010 10:10 KST

    Dinosaur eggs tell tales

    University of Toronto Mississauga scientists have made new insights into the infancy and growth of early dinosaurs.

    The oldest fossilized dinosaur embryos ever found reveal how the creatures grew from tiny hatchlings into such giant land beasts.
    The findings were made by University of Toronto Mississauga (UTM) scientists who did research on some remarkably well-preserved dinosaur eggs that have been sitting in collections for more than 30 years.
    The eggs, found in 1976 in South Africa, date from the early part of the Jurassic Period, 190 million years ago. They belong to Massospondylus, a member of a group of dinosaurs known as prosauropods.
    UTM Prof. Robert Reisz and his colleagues worked on these fossils, and it was only through modern preparation techniques that these findings were brought to light.
    Their research offers new insights into the infancy and growth of early dinosaurs. For instance, it was revealed that the future hatchlings would have been oddly-proportioned and would have looked very different from the adults of the species.
    The embryos also lacked teeth, suggesting the hatchlings might have required parental care. If true, these fossils also document the oldest record of parental care.
    “This project opens an exciting window into the early history and evolution of dinosaurs,” said Reisz.
    The eggs and embryos are on display at the Royal Ontario Museum in an exhibit entitled Dinosaur Eggs and Babies: Remarkable Fossils from South Africa.
