There have been a number of great LEGO creations built for the Iron Forge challenge recently. The seed part, or the element that each entry needs to use is the Minifig torso, sans arms, and PaulvilleMOCs makes masterful use of white torsos (one in each fossil).
While the ones on the T-rex and the Triceratops are obviously used for the skulls, trading shoulder sockets for eye sockets, you have to look more closely at the Pterosaur, to find it sprouting wings.
Great museums like the American Museum of Natural History in New York City include educational displays that span the entire history of life on earth, from samples of banded iron (chemical evidence of early lifeforms such as stromatolites) to dioramas of creatures from the Cambrian half a billion years ago to the Holocene today. But you don’t have to travel to a museum in a far-off city to see great tableaus that illustrate early life on our planet — just check out this colorful scene built in LEGO by Luis Peña. Luis’s scene features an ammonite and sea jelly bobbing along in the warm current above a trilobite scrabbling along the ocean floor. Luis has included pearl-gold pieces in the ammonite’s shell, capturing the pearlescent look of the extinct creature’s nacre.
