UPDATE 02/20/18: Well, that's more like it.
Just found out about this, but while browsing the 2019 SVP abstracts, I found this:
"CHARACTERIZING THE ONTOGENETIC STAGE OF A VERY
LARGE SPECIMEN OF ALLOSAURUS FROM THE JURASSIC OF
WYOMING WITH SUBADULT CHARACTERISTICS
VOEGELE, Kristyn K., Rowan University, Glassboro, NJ, United States of
America; ULLMANN, Paul V., Rowan University, Glassboro, NJ, United
States of America; GROVE, Joseph, Concordia College, Moorhead, MN,

A previously undescribed, isolated specimen of Allosaurus was discovered
associated in 2004 in north-central Wyoming in the Jurassic Morrison
Formation. Comprised of 65 cranial and postcranial elements, this specimen
exhibits a unique combination of large body size with subadult characteristics.
The majority of the dorsal vertebrae remain unfused, the pubes remain
unfused, the coracoid is not fused to the scapula, and the majority of the
cranial elements remain unfused. Additionally, the number of alveoli in the
dentaries (19 and 21 alveoli) and complete right maxilla (19 alveoli) of this
specimen are significantly higher than that commonly reported for Allosaurus
(14-17 alveoli in the dentary, 15-16 maxillary alveoli). Despite these subadult
characteristics, this specimen is large for an Allosaurus individual, with a
femoral midshaft circumference of 28 cm. To reconcile the discrepancy
between its size and features commonly associated with subadult individuals,
we have completed a histological analysis of the only limb bone preserved, a
partial right femur. As only the distal half of this bone was preserved, we made
a histologic section near the broken end of the bone, approximately at
midshaft. Our histologic analysis revealed expansive laminar fibrolamellar
bone forming the primary cortex with minimal secondary remodeling
restricted to the internal cortex. Numerous micro-fractures present throughout
the cortex make the identification and tracking of the few lines of arrested
growth difficult. Although closely spaced lines of arrested growth are present
near the cortical edge, primary osteons remain abundant in the external most
cortical rim, suggesting that an external fundamental system is not present.
Therefore, we conclude this large individual was still growing but its growth
had slowed down; however, it was not yet an “old” individual."
