I can help, but I don’t have live access to current news sources in this moment. Based on what I can share from prior widely reported findings, there have been notable past discoveries of fossilized embryos inside eggs from dinosaurs and early animals, such as the famous perfectly preserved dinosaur embryo “Baby Yingliang” found in China dating to about 66–72 million years ago. Other well-known contexts include Cambrian-era fossilized embryos that shed light on early animal development. If you’d like, I can search the web for the very latest updates on “embryo fossil” and summarize the most recent reports with citations.[3][4][5][8][9]
Would you like me to look up current news and provide a concise, sourced briefing with the latest discoveries and any related scientific significance? If you have a preferred region or publication, tell me and I’ll tailor the search.

Fossilized prehistoric embryos have researchers stumped -- what species did they belonged to?
www.cbsnews.comThe Cambrian Period is a time when most phyla of marine invertebrates first appeared in the fossil record. Also dubbed the "Cambrian explosion," fossilized records from this time provide glimpses into evolutionary biology when the world's ecosystems rapidly changed and diversified. Most fossils show the organisms' skeletal structure, which may or may not give researchers accurate pictures of these prehistoric organisms. Now, researchers at the University of Missouri have found rare, fossilized...
phys.orgMuch of what scientists learn about the evolution of Earth's first animals will have to be gleaned from spherical embryos fossilized under very specific conditions, according to a new study by Indiana University Bloomington and University of Bristol researchers in this week's Proceedings of the National Academy of Sciences.

www.eurekalert.orgRoughly 600 million years ago, thousands of embryos of primitive animals drifted into seawater laced with sulfides and died. Research in the Doushantuo Formation in China uncovered these fossilized embryos--among the rarest of finds both for their fragile nature and depth in past time--and new imaging techniques have provided a window into the internal workings of the most ancient animals yet discovered. Using x-ray computed tomography as well as scanning and transmission electron microscopy,...
