Facial reconstruction shows powerful Bronze Age woman’s serene expression and huge earrings
Read more: Facial reconstruction shows powerful Bronze Age woman’s serene expression and huge earringsLive Science has a story about some facial reconstruction performed on a Bronze Age woman’s skull.

The find was described in the journal Antiquity earlier this year. A “powerful, maybe even frightening” woman buried with a silver diadem in Bronze Age Spain now has a virtually reconstructed face that shows her wearing…

Mazon Monday #89: Jeletzkya douglassae
Read more: Mazon Monday #89: Jeletzkya douglassaeThis is Mazon Monday post #89. What’s your favorite Mazon Creek fossil? Tell us at email:esconi.info@gmail.com. Of all the millions (yes, millions!) of Mazon concretions that have opened over the years, only two specimens of Jeletzkya douglassae are known. That might make it the rarest of species in the Mazon Creek biota. It’s considered to be a squid. Talk about soft bodied animals… its only hard parts are the radula and the pen. For as rare as it is, it has a Wikipedia page! It was described in 1968 by Ralph Gordon Johnson and Eugene S. Richardson, Jr. The description…

Weird Tracks in Texas Indicate Giant Sauropods Walking on Their Front Feet Only
Read more: Weird Tracks in Texas Indicate Giant Sauropods Walking on Their Front Feet OnlyNature Science Alert has a story about sauropods. Some strange footprints, found near Bandera, Texas back in the 1930’s, could show swimming behavior in sauropods. That theory dates to a letter written by Roland T. Bird in 1940 about front foot only prints made by sauropods. A paper in 2019 reexamined the question, but at a different locality – Coffee Hollow, part of the Glen Rose Formation. That locality was discovered in 2007 and dates to the Cretaceous Period. “They were all typical forefeet impressions as if the animal had just been barely kicking bottom.” With time, Bird’s interpretation of…

Nature: Ancient Pine Cone Trapped in Amber Shows a Super-Rare Form of Plant ‘Parenting’
Read more: Nature: Ancient Pine Cone Trapped in Amber Shows a Super-Rare Form of Plant ‘Parenting’Nature ScienceAlert has a story about a pine cone preserved in amber. The fossil, which dates to about 40 million years ago during the Eocene, shows a rare form of parental care in plants. The seeds in the pine cone can be seen to be germinating and sprouting greenery before the cone has fallen to the ground. This rare “behavior” is called “precocious germination”, or “seed viviparity”. See all the details in a paper in the journal Historical Biology. Usually, pine cones fall to the ground and then open up when the climate becomes warm and dry, releasing their seeds…
