A new avialan theropod from an emerging Jurassic terrestrial fauna

Abstract

Birds are descended from non-avialan theropod dinosaurs of the Late Jurassic period, but the earliest phase of this evolutionary process remains unclear owing to the exceedingly sparse and spatio-temporally restricted fossil record1,2,3,4,5. Information about the early-diverging species along the avialan line is crucial to understand the evolution of the characteristic bird bauplan, and to reconcile phylogenetic controversies over the origin of birds3,4. Here we describe one of the stratigraphically youngest and geographically southernmost Jurassic avialans,Fujianvenator prodigiosus gen. et sp. nov., from the Tithonian age of China. This specimen exhibits an unusual set of morphological features that are shared with other stem avialans, troodontids and dromaeosaurids, showing the effects of evolutionary mosaicism in deep avialan phylogeny.F. prodigiosus is distinct from all other Mesozoic avialan and non-avialan theropods in having a particularly elongated hindlimb, suggestive of a terrestrial or wading lifestyle—in contrast with other early avialans, which exhibit morphological adaptations to arboreal or aerial environments. During our fieldwork in Zhenghe whereF. prodigiosus was found, we discovered a diverse assemblage of vertebrates dominated by aquatic and semi-aquatic species, including teleosts, testudines and choristoderes. Using in situ radioisotopic dating and stratigraphic surveys, we were able to date the fossil-containing horizons in this locality—which we name the Zhenghe Fauna—to 148–150 million years ago. The diversity of the Zhenghe Fauna and its precise chronological framework will provide key insights into terrestrial ecosystems of the Late Jurassic.

a, Photograph.b, Line drawing. ch, chevron; cv, caudal vertebra; dv, dorsal vertebra; gs, gastralia; lf, left femur; lfi, left fibula; lh, left humerus; li, left ilium; is, ischium; lr, left radius; ls, left scapula; lt, left tibia; lu, left ulna; mI to mV, metatarsal I to V; mcI to III, metacarpal I to III; pt, proximal tarsal; pu, pubis; rh, right humerus; ra, radiale; rc, right coracoid; rf, right femur; rfi, right fibula; ri, right ilium; rs, right scapula; rt, right tibia; st, sternum; un, ulnare; ?sv, possible sacral vertebra; I-1 to I-2, manual phalanx I-1 and I-2; II-1 to II-3, manual phalanx II-1 to II-3; III-1 to III-4, manual phalanx III-1 to III-4. Scale bars, 20 mm.

Extended Data Fig. 2 Additional anatomy ofF. prodigiosus, IVPP V31985.

a, Right hand.b, Close-up of the left metacarpals.c, Pelvis.d, Proximal ends of metatarsals. is, ischium; lc, lateral condyle; lct, lateral condyle of tibiotarsus; li, left ilium; mc, medial condyle; mct, medial condyle of tibiotarsus; mcI to III, metacarpal I to III; mtI to mtV, metatarsal I to V; ob, obturator process; pa, pubic apron; pb, pubic boot; pp, posterior distal process; ri, right ilium; I-1 to I-2, manual phalanx I-1 and I-2; II-1, manual phalanx II-1; III-1 to III-4, manual phalanx III-1 to III-4. Scale bars, 10 mm.

Extended Data Fig. 3 Comparison of the pelvic anatomy ofF. prodigiosus with that of other selected paravians.

a,b, Photograph (a) and reconstruction (b) of the pelvis ofF. prodigiosus.c–f, Reconstructed pelvis: avialanAnchiornis (c; modified from refs.7 and87), troodontidSinovenator changii (d; modified from ref.4), avialanArchaeopteryx (e; modified from ref.4) and dromaeosauridMicroraptor (f; modified from ref.4). ob, obturator process; pdp, posterior distal process; ppp, posterior proximal process. The arrowheads denote the constriction at the base of the obturator process. Line drawings are not to scale.

Extended Data Fig. 4 Morphometric analyses of limb-bone length across the Mesozoic theropod phylogeny.

a–f, Binary plots of the first three principal components (PCs) of the phylogenetic principal components analyses of the six limb segments (a,b), forelimb (c,d), and hindlimb (e,f).

Extended Data Fig. 5 Time-scaled phylogeny showing the position ofF. prodigiosus through parsimony analyses.

The phylogeny is the strict consensus resulting from maximum parsimony analyses. The bootstrap and Bremer values are denoted in normal and bold italic fonts, respectively. Thick lines represent the first and last appearance datum of the geological stages or epochs in which a given species was discovered.

Extended Data Fig. 6 Dated phylogeny showing the position ofF. prodigiosus through Bayesian tip-dating analysis.

The phylogeny is the majority-rule consensus obtained from the posterior trees of Bayesian tip-dating analysis using the fossilized birth–death model. The error bars at the nodes represent the 95% highest posterior density intervals. The shaded circles at the nodes represent the posterior probability of the corresponding clade.

Extended Data Fig. 7 Comparison of the hindlimb proportions ofF. prodigiosus with those of stem and crown groups of theropods.

a,b, Ternary plot of the length proportion of the hindlimb segments (femur, tibia and metatarsal III) of Mesozoic theropods (a), and with the inclusion of crown birds (b).

Extended Data Fig. 8 Additional vertebrate fossils discovered in the Zhenghe Fauna during the 2022 fieldwork.

a,b, Teleostei indet. (Actinopterygii: Neopterygii).c–h, Testudines indet. (Reptilia: Pantestudines).i–k, Allochoristodera indet. (Reptilia: Choristodera). All photographs were taken in the field shortly after the discovery of the corresponding specimens.

Extended Data Fig. 10 LA-ICP-MS concordial age plots of the fossil-bearing horizons of the Zhenghe Fauna.

a,b, Samples from the tuffite layers deposited just below (c, PM702-1) and above (d, PM701-4) the IVPP V31985-bearing horizon.c,d, Samples from the ignimbrites that underlie (a, Bdx03) and overlie (b, Bdx04) the fossil-bearing sediments.
