Neanderthal Fetus Mirrors Modern Babies, but Limbs Hint at Faster Prenatal Growth

High‑resolution micro-CT study of Sesselfelsgrotte Neanderthal remains shows an eight‑months‑along fetus whose skeleton resembles a modern human fetus, with limb bones forming somewhat faster than the skull; two other young Neanderthals’ teeth reveal early signs of a metabolic bone disease, suggesting a systemic mineral metabolism disruption between late pregnancy and early childhood. The researchers caution that the data are fragmentary and comparisons rely on modern humans, so the exact pace of Neanderthal development remains uncertain.

Revealing the Growth Journey of Baby Dinosaurs: From Football-Sized Hatchlings to 3-Tonne Teens

New research on the bones of Maiasaura, a minibus-sized dinosaur, reveals that these creatures were warm-blooded and highly active, capable of rapid growth and levels of activity comparable to modern mammals. By studying the bones of juvenile Maiasaura, researchers found that the size of the foramen, a hole through which blood enters the bone, was an indirect measurement of blood flow rate and energy usage. The study showed that young Maiasaura had significantly higher blood flow rates and required more energy and nutrients for bone growth compared to adults. These findings support the idea that dinosaurs were warm-blooded and active animals.

Ancient Woman's Leg Injury Led to Unusual Bone Growth, Experts Discover.

Anthropologists have discovered a 3-inch long "rope-like" extra bone growth on the skeleton of an adult female in Constância, Portugal. The bone growth was caused by trauma and is the first documented case of myositis ossificans traumatica on the area of the pectineus muscle. The extra bone growth would have been extremely painful and would have made it hard for the woman to move around. The researchers found that the extra bone growth was between 6 weeks and a year old.
